Best Exhaust options for ESS supercharged csrs

[Tunerjones]

So I've been doing a lot of research and trying to squeeze the most amount of horsepower out of my girl.

Car:
E92 M3
Turner Test pipes and oem exhaust mod

I do not daily the car, so the loudness of the car isn't a huge factor for me.
I have looked into getting an x pipe for the car.
I have also shopped around the idea of having the mufflers deleted, 2.5 pipe waddled in place and 4 inch quad tips on the end.

What I'm asking is, has anyone built custom 3 inch exhaust for the m3's through a muffler fab shop? Has it produced positive tested HP gains on supercharged cars?

Let me know if you upgrade and want to get rid of your current exhaust setup. I want to try test pipes but I'd like to keep my stock parts.

[Tunerjones]

Definitely will do. I love the test pipes. Surprised this thread hasn't gotten more attention

One of the best values is our full agency power system. Catback comes complete with resomated mid pipes to help with drone, and a retail price of only $2500 for the whole system, its a bargain! AND forum members get better deals than that as well

In stock, and ready to ship with the titanium tip option, or the stainless tip.

Shoot me a PM for your special pricing.

Do you have any exhaust videos of the setup? Looking at that for mine as well. Thanks 90856674zero3

I have full 3 inch muffler exhaust, ARH long tube and xpipe. The sound is the deepest and no rasp.

i have and afe catless mid pipe and borla atak. with the ess 625 kit. i put the atak on a couple months ago but now im debating on selling it. its rather loud.

I have a full Akra, It fell on its face at about 6.5k, I reached out to ESS they said it was my Akra, I went and got a costume tune and it sings to 8.2k. I ran the Borla ATAK with stock cats and it sounded great and ran just fine. I was afraid I would burn up the cats. A friend has high flow cats with the Borla ATAK and it sounds nice (ess 625). With no cats the Borla will be loud.

If you want most power, get the ESS decatted xpipe or the Bimmerworld race xpipe. Both have 'forward' placed crossovers which generate the most power.

As far as muffler, maybe keep your stock one until you adjust to the volume of the BW race xpipe and then go from there.
