Hello all, its been 2 years since I sold my E90 and I miss this forum soo very much..
Anyways I found a ton of files on my 328 which I thought I lost..
Prior to this exhaust, I had a muffler delete done as my exhaust for over 4 1/2 years. Sounded good but a little too loud in town in my opinion.
Whats been done.
The mechanic cut open the muffler, added titanium pipes and had them welded directly to the tips rather than have a curve inside the muffler in order increase flow. He also removed a bit of sound deadening (I asked him keep it quiet).
Results.
Sounds much louder than stock raspier on higher RPM, but definitely quieter compared to muffler delete.
He suggested I remove the resonators prior to install in order to get the best out, but I refused since I feared drone.
I felt an definite improvement on acceleration once you go over 4000RPM.
In the past my mechanic (RayTeam Automotive in Waltham, Mass) modified 2 of my friends 335's and my god it sounded glorious. There was a huge difference when doing the Golf Tee Mod.
Enjoy and check out other of my videos if interested and into Cars!
