Aprilia RSV4 RF | Austin Racing GP1R vs SC Project Exhaust! 

I'd say the SC project exhaust, but i'm a sucker for color changing titanium.

3:33 - AR 5:45 - SC

The SC, it has a more pleasing angle in relation to the tail piece

a fly-by will be a good idea

Here again, because of you Uncle IB, I’m purchasing my first Liter bike (2013 RSV4 RF)

I got a SC-Project myself sometime ago when I didnt even know what SC-project was, bought it for the good look, and damn it sounds awesome. Still use it with baffle, but when I open my Hornet up, its like thunder! From now, only SC project will go into my bikes.

damnnn that SC project exhaust tho😍😍...I've betrayed you 650ib I'm sorry😞

The two exhaust have incredible sound. Watching your videos here from Brazil. thank you

I've got the Austin racing on my RF it has that perfect rumble !! combined with the quickshifter when on full gas just totally blows your mind wicked !! good work ib !

Even after 3 years I still love this video.

I like the AR more!! It sounds so menacing.

Dang, needed a fly by at the end there. Hear those beast under load and blipping through the gears. SC looks great.

I can't thank you enough for this video!! SC Project has the color changing plus it's looks.... but the Austin has a beefier sound to it and it matches on color. You've made my decision hard :P

I like the AR look on the RSV4, the SC may just edge it on sound tho

both sound amazing I like the low in growl

thank you so much for this man! getting an RR soon and was trying to decide between these two

cool, now all i need is to play this video over and over again before i make decision. thanks for sharing man!

I have a rsv4 and I thank you 650 for making this video because I still have stock exhaust so this will help me decide which one to buy

Awesome video well done.my favourite exhausts!!!thanx for the video

Wow love aprilia's! Great vid. Looks like you wiped them down before vid, much appreciated.

The sc sounds and looks better in my opinion ;)

Great Video, just what I needed to see and hear. They both look and sound great, the SC just pips it Imo. So SC is what I'm gonna order. Thanks for the review Guy's. Thumbs up from here in UK loving your work.. xD

Cheers bro nice test. Look forward to you testing our range topping GP1RR 70mm straight through!!!

@8:00min. the whole world changed. I forget how good the RSV4R(F) sounds. Play. Awesome video 650ib

Thank you!! Great videos by the way !! Love you guys!!

They both sound beast.

i love your videos man

Austin Racing gp1r for the win! great vid 650ib... keep them coming

just purchased a GP1RR no baffle for my 2020R1 end of discussion love that AR rumble and look 👌

Hey 650. In the "looks" department I lean toward the Austin unit. It simply has more character. But I prefer the sound of the SC. It reminds me more of my Competition Werkes unit. Though they both sound amazing. But we all have our personal preferences. There is no right or wrong. I love making SOUND video's of our beloved RSV4's. The best sounding machine I've ever heard. Much better than the new V4S.

The sounds are very similar but I love how the Austin racing just looks like it was custom made for this bike. It matches the bikes color scheme perfectly

I love the Austin power .. both sound very similar I love the way the Italian stripes on the exhaust match the bikes stripes and the exhaust is over all better looking for that bike

His Soundes great in higher RPMs but yours has the best Growl I've ever heard,,, hopefully the Color will come on your exhaust

Sound is on point either way, but the AR has the color matched logo going for it. You got to coordinate!

The problem with exhaust videos is that they'll never truly capture what you hear in person. That heart palpitation inducing sound that comes from an Aprilia can only be experienced in person.

650ib thanks for the response. I am going for the Austin Racing slip on, cheers

I think the AR looks better on the bike. Honestly not a dramatic difference in sound to me.

AR color on the sticker match bike perfectly and sound is great...SCP is also good but I would give edge to AR

That sc exhaust sound a little louder but has a straight deep sounding rumble. Austin has less noise but more of a vibrating deep sound. They both sound similar but has it own character to the rumble and they both look awesome.

SC project definitely the perfect suit for this beast!

thks for the good sound comparison, I just purchased the sc project for my s1rr and have not gotten it in the mail yet. I'm thinking about picking up an rsv4 rf and between thee two the ARgp1r is more aesthetically appealing & sounds better in my opinion so i'd be considering it if I end up picking up the rsv4

AR looks the goods and sounds fantastic

Thank you ib, that's great. 😊

amazing sound

ill be seeing you tomorrow at the progressive motorcycle show ! i look forward to meeting you !

I have never been a fan of V4 engines but god they sound beautiful, I love the sound of both of those exhausts, think I may be converted.

They need to be combined somehow as the SC Project is gorgeous but the sound of the Austin is awesome!

so sick👍

how about a flyby for both iB? SC for sound, AR for looks

I'd go with the Austin racing personally...and the lil Italian decal on the side of the muffler is a nice touch too.

The AR looks like it was made for the bike and is plenty gnarly sounding. The SC probably sounds a bit more aggressive too most, but in person that bike sounds AmazinG with the stock can so it's really just preference. Have a custom full exhaust done on that bike and it's ferocious! 👍

Both super similar. I don't know much about either. The color change looks sweet on the SC Project. They sound pretty similar but because the RC sounds quieter you can hear more motor. I'll go SC AT REV and AR at idle. Would like some more vids on the FZ10!! I've got one and can't decide on an exhaust and a few other mods. Going to Superbike Unlimited on your recommendation for ECU flash!

The AR looks better on that bike. Not that much diff but I think the SC sounded better. Nice vid and comparison. So rare to see the same bike/motor side by side. Peace.

They both sound great but I still love the Austin racing gp1r. Has a throatier grunt to it sounds so good 👍🏼😉

Hey good buddy! stay safe

What are the performance and weight specs on both of them?

cool cool stuff!!!

it's pretty close but have to go with Austin.

hey 650 love your content Keep It Coming brother what are your thoughts on the Ducati Supersport models year 16 or 17

Question about the mid pipe, is there a Cat converter there? Or is it a straight pipe once these slip ons are installed?

Both exhausts sound great but I'd have to go with the Austin Racing exhaust because it sounds more ferocious to me!

Im feelin the AR system.

i had a 2015 s1000rr want to change to a newer bike, im stuck between 2017 rsv4 rr and s1000rr, which one is best

I love both❤️

I like the Austin Racing sound, to me it has a bit more bite :-) And yes, I am wearing a gaming headset lol. 650ib's windscreen is a nice upgrade on the RSV4.

Thanks for the vidéo....i'm on my way To buy an Rsv4 2014 but im wondering if I'll keep the SC exhaust Already mount on it or ask the seller To take only the original exhaust! What do you think?

i like the austin racing better i think it enhanced the character sound of the v4 better well thats my opinion i love ur videos man and all ur bikes ofc

Think both sound good 650ib. They're not hugely different. What I'd like to know is what you think of the build quality of the two systems. Does one edge the other?

sc project it is... looks beautiful... sounds even more beautiful ❤

I see a lot of comments saying the sc project. But I actually prefer yours. It has the green white & red that matches the underneath of the fairing. The initial startup sounded better on the gp exhaust. But when u revved the sc project exhaust it sounded louder with more of a rumble. All in all. If I had that bike I'd go with your setup IB. But I would def change the reservoir to his. It compliments the bike quite nice

Both sound awesome. The AR is definitely a bit more aggressive as the SC is clean. Both loud and they would be good either way just depends on how mean or how clean you want to be

Hey bud. Did you put a Race ECU or tuning on them? I’d assume they are decat slip ons? Let me know, thanks

The Aprilia and the Austin Racing Exhaust has the best sound. I heard it in person and gave you compliments about it. But SC Project exhaust still sounds good.

What up 650ib!

Both exhausts look and sound great...however...gotta give the prize to the Austin Racing GP1R for looks and sound...twin beauty!

that SC sound nice

Is that sc project the 60mm 65mm or 70mm can ? I can't decide on size for my tuono which would be louder

The AR doesn’t look as good as the SC Project but sounds heaps more aggressive. It’s the AR for me 650.

The SC project is definitely a cleaner look and a cleaner sound. But that super aggressive Austin racing grows on you quick!

Bike sounds so damn good

I'd go SC for sound and it looking a bit longer and thinner, I'd bet your low end is going to be stronger. I've got an Akra on my 17 Tuono. I went Akra thinking it's the best, most specifically designed for the bike choice. That's not necessarily true. Check the cheap option, Arrow Pro Race Nichrome. I may have to try it out. Looks awesome in black and sounds pretty crazy. Nice vid 650 ib!

Which one makes more power, and where?

AR looks the part and sounds the part imo

gp1r for the win. thx for the vid.

On this bike, I prefer the GP1R. Just sounds meaner, deeper and more round to me. Beautiful!

dam both very nice, I think the AR looks nicer on the rsv4 but that sounds of the SC is beautiful

is R1 louder than the rsv4? does R1 sound better?

It's close, but I have to give the nod to the SC Project slip-on for it's sound quality and the purpose-driven styling (plain, but functional). Ride aware, and "Keep on keeping on!"

AR can hear the V4 thumping heartbeat

In my opinión AR GP1R, looks very good in your bike 👍🏼

I like the AR look and sound it growls, I’ve heard the aprc with an sc in real life it was a little tinny, still wicked though.

The Austin Racing sounds better than the SC project in this video. From what I can tell is that the AR is the GP1R model. There are other types available, such as, the GP2R and the V3 and each of their colors may be customized. I can’t tell which SC project is in the video but it looks like possibly the CRT. Great video! What would look good if you had a dB meter to measure the sound levels during the video. Awesome to see these two brands side by side! Thanks!!!

Glad to see its not a Brock ! But why dont u buy a akrapovic ? Would love to see that . And i would go for the sc project . U give great content man ! Maybe one day we ride togheter.

Austin racing exhaust dude. Looks the part with the aprilia also. In terms of "note" they both seem to be very similar. I think 90% of the analysis should go to the sound, not the look because the look is subjective and they both look trick anyway. I prefer yours Ib, matches your bike perfectly and it is throatier/louder. Nice video love you man

Ar. Absolutely. I love the bass sound more!

Wiche one is louder bro the GP1R or SC PROJECT CRT?

They both sound great but it Hass to recent detail wow awesome

Need to do anything with ECU? Effect fuel economy?

SC by far! What's up with the make shift mid pipe on the AR looks like it is pieced together while SC is one uniform piece of art...

the Austin is more my taste, but I wouldn't say better or worse. The SC sounded a little more "cammed" if that makes sense. I might very well prefer the SC exhaust whilst riding the bike in the peak power range. Cool video fellas. I wish you would do a quick sound video of the EBR, my favorite of the bunch.
