G80 M3 JB4 Review 

You’re very welcome that’s exactly why I made it! I know there’s a lot of us out there that feel the same way.

Appreciate it!! 💪

Glad to help! Join out FB group we share tons of info Terry is in there himself

Thank you!!! Truly appreciate the positive feedback. Congratulations on the new purchase. I too had the same concerns as you as far as exhaust modifications, on my car I have a single midpipe only with stock muffler and downpipes. Imo the sound and performance gain is perfect for a daily driver .

@@elgapitan Thanks man. Which Midpipe? Does it create really loud sound at cold start? If it doesn't , please link me my brother!

@@jaycampbell333 x-ph.com/mad-bmw-g8x-m3-m4-single-midpipe-brace-included-mad-5048/ This is the one I have cold start isn’t bad I start it everyday in my garage at 5am and doesn’t wake anyone up lol. They also have resonated version now.

Well you know which one got my Vote!

Racechip is great, noticeable performance gains

Thank you!

Go for it I have a single mid pipe on mine 👍

In NJ, it’s just one plug that’s a PITA but can be done with a little patience.

@@elgapitan I’m in NJ too; I have a 6mt I saw your fb post about custom maps. How much would you charge me to install it?

@@roma5733 I didn’t even have the time to do mine lol my boy installed it for me at AMS in linden

Always in sport plus, we have resolved the throttle closures in custom maps. Join our fb group we have a group chat

@@elgapitan No way!! I joined last night! Waiting for approval I guess?

Aaahh thats so awesome you guys figuit out!!

AWD

@@elgapitan do you know what times a RWD map 3 would run.

@@shaz8365better on rolls, little slower on drags

Thank you!

It is not

If something big warranty wise would happen they would know

The ECU will show more boost fueling etc .BMW can read it .the standard parementers have been exceeded and it gets logged .

Thats what i heard and was still worried bout piggyback@@sf2942

Yes

​@@elgapitanhow do u know how much e85 to put into it. Do u just do a little then do the rest 93 Oct? Sorry I'm new to all this

Use a calculator to be sure but typically 4.5gal of ethanol to a full tank of 93

I appreciate that!

I'm just not understanding the comments about Catless downpipes. I've seen dyno charts where the downpipes actually smoothed out the power curve with the Jb4. I'm sure it needs to be dialed in differently with downpipes of coarse but it's gotta be easier on the turbos to breathe more freely than having to run more boost to net the same gains. Either way, I notice there's certainly a lot of confusion about this topic. A lot of guys say the same about the downpipes not making much of a difference in power between the Bootmod stage 1 map vs the Stage 2. Then you have some guys running custom tunes claiming they gained 80whp. One thing I'll say everyone seems to agree upon is if toy want big power E85 mixtures "E30+" is the Way

@@MichaelSchwab-nk4rm you’re not wrong! I personally feel the downpipes cause too much of a disturbance without an actual tune for most. Definitely requires a custom map 6 to run optimal, I do however think the AA catted options are a good compromise. I may bite the bullet on a set!

​@eric__padilla Yoy gonna order the catted? Naah just get the catless! The catted still throws a cell so you might as well

@@MichaelSchwab-nk4rm not the Active autoworks ones! Guaranteed no CEL
