Catback Exhaust Volume Inquiry

[GOFAST M3]

Hey Everyone,

I am about to pull the trigger on a 2012 e92 M3 6MT, and my first mod will be an exhaust.

My 2013 M3 DCT had the Borla ATAK, otherwise completely stock, and I loved everything about the exhaust note, volume, and lack of drone(to my ear).

This time around, I am almost certain I will eventually get HF catted x-pipe and a tune(maybe even a supercharger down the road).

It was tough, but I found a Borla S-type available, and am thinking that will be a better pairing with the x-pipe than the ATAK for my taste.

Does anyone have any experience that could help me make up my mind on which axleback to get, namely how the s-type sounds with an x pipe?

I could find any videos, appreciate any help you can provide.

Thanks

it'll probably be as loud as the attak if you're going to run a catless xpipe with the S-Type

I'm going to run HF cats in any x pipe I get, but I think you're right, it's going to be relatively close in volume either system I get.

Maybe something like Dinan or MPE would better suit my taste with catted x pipe.

Thanks

you'd probably hate the MPE with any xpipe. it's too raspy for some.

Not unless you wrap the X-Pipe. I gotta get a video of mine. Will hopefully soon.

The MPE with the wrapped X-Pipe sounds amazing with a very good quality rasp only after 3k and if you're really on it.

I have a the Borla S-type on my e90. Got it direct from Borla when they were doing close out pricing for like $600! E90 specific S-type and ATAK are now discontinued. I have it paired to a Macht Schnell catless x-pipe (so just two resonators). It sounds great with absolutely no rasp which I’m happy about. Pretty deep full sound. It can be quite bassy between 1700-2300 rpm. A quad resonated x-pipe or one with high flow cats may tone that done a bit but I’m unsure. I’ve actually played around with the idea of switching to an x-pipe with quad resonators to see the difference.

I am in the exact same boat as you - catless MS X pipe with an Active Signature axleback. I’m debating adding two resonators or adding two high flow cats to the MS X pipe to reduce the bassiness from 1700-2300. I don’t mind the volume, but the bassiness gets transmitted into the cabin as NVH which I would like to reduce. Been trying to find someone who’s had both a quad resonated x pipe and HFC x pipe to see which one I should do.

I’ll let know you if I ever make the switch. You can just check it out as I see you’re in Houston too.

Sounds good! I’m looking to either add the cats or resonators in the next month or two, will let you know when I do if you wanna see as well. Btw, are you in our local Houston e9x chat?

I’m not. Is it on here or another platform?

Thank you guys for the comments, I was not able to get a Borla S Type after all.

I am in Houston too, would love to be a part of the M group here once my car arrives in a few weeks.

Thanks again, guys.
