Some people prefer not to spend 3k on a exhaust, but they also prefer not to gut the exhaust system too.

I spent 1500$ on my Borla ATAK and the exhaust tone with catless DP sounds completely different then the straight pipe gutted stock exhaust, almost F1 racecar like. Not to mention aftermarket exhausts are generally lighter and made of better quality metals.

Im not trying to say straightpipe is the way to go, just saying $3k for sound is not worth it.. i have heard catless+stype and it sounds real solid. But im content with my catless+muffler delete

I'm considering a Yas Blue M3 now...damn you people.

Well that escalated quickly. Nothing wrong with the M3/M4 except the sound they make . However for driving and performance they are damn good.

Never claimed it would sound like a rice rocket. Just claiming that that is a mod that is not uncommon.

To be clear the Akrapovic is not for me by any means. But I would never on any car especially perform a modification that detracts from the value of the car. And it is factually impossible for a straight pipe with no mufflers not to drone.

That being said, I don't make decisions or opinions for anyone else but me. As long as your straight pipe works for you that's great, that's all that matters.

I was more stating that if someone is eyeing the 3k exhaust option, the suggestion of just gutting exhaust does not make sense

[MrF30]

I did a muffler delete but kept the resonators. It does drone, but it wasn't as bad as I thought it would be. Truthfully, maybe it's because I kept the resonators or whatever, but the drone seems fairly minimal on mine maybe because I play my radio. It's really only noticeable when I'm driving stop light to stop light in the city. I had a muffler shop follow Fabspeed's design...well, it's really the only design a shop can really do.

Akra is a work of art, attention to detail is impressive. Turbo would be the more sensible mod considering it will add a nice bump in power. Either way, we are here to help with tuning/installation.

[Bestia]

I respect all the opinions and mine was based on dishing out some good $$$ for my Tubi exhaust on the M5. The sound was intoxicating, but in retrospect, I should've spent that money on Evolve headers since I already had their tune. I agree with ENZO that the turbo would be a more sensible option.

[zinner]

Watch that if you want to understand how much you are uncorking with an exhaust.

[Enisada]

If you really are not satisfied with the sound do the exhaust. If you want more power do the turbo.

Personally I would do the turbo though.

[shivaswrath]

Well the M3 sold, so I'm back to this debate. And leaning towards the turbo, since my car has a 2012 turbo and there would be enough gains (and no need to worry about fueling) with a simple pure stage 1.
And thanks Info@EnzoPerformance for offering to tune and install, I'll get it sorted out and bring it by for a fresh retune too (more burble+bigger turbo=happy shivas).

Nope, already talked to them, I am exactly where you are at, I believe we got ENZO tuned around the same time as well, we have similar mods.

They will tell you their stage 2 flash tune will support the stage 1 turbo upgrade, just pick up a jb4 set it on map 6 as a boost control around 16psi and that is pretty much that.

I talked to Chris about it several times. I already have the JB4, dont bother spending the money on a reflash...

Ah ok, yes Chris mentioned to do a JB4 as well, just threw me since I thought the whole point of a flash is that I don't have to "hack in" with a JB4.

Ya not sure why but I'm guessing the stage 1 is not a big enough change and the flash supports it, just need the jb4 to regulate boost. He stated for the rest the ECU flash has full control. Maybe something to bring up to them again now since its been about a year and new things have happened with tuning.

You should look into the CG Precision exhaust. I chose this over the akra and couldnt be happier. Fitment and quality is top notch!

Completely off topic and sorry to bring up a old thread but I wouldn't need to forge any transmission or engine internals for a pure stage 1 turbo upgrade?
I have a 2013 F30 335i with catless dp and a Jb4 with 40% E85. Can my transmission handle all that torque?

Yes trans will be fine with ps1, even with moderate ps2. BUT before ps1 you should get IC, Intake and CP that you didn't mention them on your post.

Indeed, only thing that's falling apart for me right now, after 10k miles on turbo, is the god damn DV.

Since BMW installed the turbo, I couldn't "give them" The GFB DV.

Will be wasting time and money to rectify that soon...(and yes, IC/Intake/CP are necessary too).

Shiva!!! That was your chance, I would have made that happen. Honestly even on stock cars besides a charge pipe its the single most important mod.

By the way, have you sorted out your tune and or flash? What are you running now?

You got any videos of your car?

Dejan!!
I know. Sort of rookie mistake. Sort of...I knew Bmw wouldn't cover the GFB.
The tune was redone by CB Tuning/Eurodynamic, I had to take off the JB4 because of the issues with stacking ..... It runs strong as hell. Dynoed 350/381 on dyno dynamic, so around 400 on a dyno jet...(I didn't take pictures of the dyno but will when I go back after the DV install).

I'm happy with the flash only strategy...smooth and no lumps or surges!
