C7 Z06 ARH 2” longtube headers catted x-pipe lt4 corvette cold start and burnouts 

Hahahaha 😂😂😂😂

Same

Thanks, I agree I don’t like my cars stupid loud. It sounds tough at idle but doesn’t scream until your full throttle.

Yeah my buddy had Castles’s arh with corsa extreme on his lt1 c7 it was unreal how loud it was, I prefer the catted x pipe because the tone you get from them as the cats actually change the sound. If you want it as loud as possible though you will probably want to go catless, that combo will definitely release lots of bald eagle. 🇺🇸

The only reason I like the catted c pipe is I think the tone is a little better and I didn’t want the Fuelly smell in traffic from Castles’s, my buddy had Castless and it sounded great though too so I think it’s all preference

It doesnt compare... go for the Z06. Lol

I had the same thought for months....bought a z06 anyway. 😂 82k check and now I'm happy.

​@@MacDaddyC7Z06 nice! Im debating whether to get a c6 gs or a c7 stingray. They're both around my price range

@@Godssoldier. I would definitely get a C7 GS if you can. That wide body makes a big difference.

Yeah I had a stingray when they first came out and made the jump to the z06. If I thought the lt1 was a great motor. I had some bolt ons on my car and it was great as a driver, but if you want a powerhouse the z06 is the move. The lt1 just doesn’t give you the violent power like the blower motor does.

None at all, I always found the opposite to be honest, the catless seem to give gassy smells more from what I’ve noticed in the cars I’ve been in, that was actually one of the factors that made me want cats

@@serviceonehvac7123 thanks for the reply! Makes me more excited to get my high flow cats x pipe installed on my C6.

The car has one set of cars that are high flow cars welded into the x pipe, so it no longer has 2 sets of cats like factory

I didn’t notice any loss but I definitely noticed the gain in the top end

Some Idiot With A Z06 yes that is factory npp exhaust

Brian Hancock it’s a full header and catted x pipe system from American racing headers

Surface to Air geeez so what the hell does the catless one sound like??!!!

The cats hold back power a bit but I think it’s worth the 1 hp, the exhaust doesn’t get the fume smell at lights etc, and personally I like the exhaust tone. If you’re looking for every ho you can get though I’d just go with the catless

@@serviceonehvac7123 Ok thank you for the answer i just dont want stupid talking during the inspection in Poland about exhaust without catalyst and I'd rather not spray petrol from exhaust everywhere 😅

​​@@serviceonehvac7123I'm trying to get the same set up for the same reason as yours. This video proves catted versions are still loud AF. I'm just curious how much louder is the catless. The difference doesn't seem that significant and worth the smell.

Bc its a new exhaust, its burning off oils

No the car did not need to be tuned however we are going to tune it as there is some lag in throttle response right off idle, I’ve been driving it with no issues for over a year but i am going to tune it to see if we can improve the throttle response. As a side note I did the same combo on my 2015 z51. I never tuned that car in the 4 years I ran it modified and never had a single issue, I even broke the rearend in that car and the dealer warranted it with the headers installed. In all honesty I don’t feel the lt1 needed to be tuned but I do feel the lt4 will benefit from tuning. It’s going on for a pulley and tune soon so I’m going to make another update video sometime this month

Firehawk1218 I just left a public comment that should help answer your question 👆🏼

@@serviceonehvac7123 Thank you very much for getting back to me and for all the great info. Your car sounds outrageous! I have a 2019 Z06 and was considering doing this mod. I've heard conflicting views on whether or not to have it tuned and I figured why not ask somebody who did it. I also wanted to keep the cats like you did so that the car wouldn't be too obnoxious. How is the car under normal driving, any drone? Thank you again.

Would you say putting a ported throttle and a tube would really make a difference. Or just a tune after the headers should be good? I feel like after I put the exhaust and the intake a tune alone with those bolt ons would make a difference in the throttle lag

Firehawk1218 the drone isn’t bad at all and I have factory mop so if I put the car in stealth mode it’s basically silent which is what I do on long rides

Vettes have 2 sets of cats, primary cats where the headers are and secondary is where the x pipe would go

@@jjpenalifts thanks for the clarification!

Yeah as Jonathan said it’s only got hi flow cats in the x pipe, the ones off the manifold go away

@@serviceonehvac7123 how do you pass emissions?

Stock mufflers just has the arh long tubes with the arh catted x pipe
