i heard something about vishnu (maybe eisenmann) wiring the o2 sensors fooling them on a high-flow turbo back


if you cant tell a 335 exhaust upgrade from a '96 integras, you know theres a problem, i guess what im trying to say is listen to a bunch of sound clips, id go by sound, there is plenty ways to get minimal HP gains, i wouldnt sacrifice that tamed growl for 3 whp

Im wondering the same...the Germans have upped the ante a bit, so the old resistor in-line trick might not work anymore. The race exhaust for the E60 is what I want to see replicated, but its going to be hard giving an inline 6 with turbos that raspy i-eat-small-children sound that makes the V10 sound like teh sex, and still having the cats in place.

Interesting... I'm not looking to radically change the sound of the 335i exhaust note. It does sound fine-- just looking for something with a little bump in improvement and backpressure so I can run the stage 1 Procede map.

For that application, the Milltek might be fine for me.

Eisenhaus

I almost got the Ultimate Racing exhaust for my e90 until I heard the complete exhaust system offered by Eisehaus for the 335i...oh...my...god...unbelievable...go to their website if their video clip doesn't convince you...then you need to stop smoking crack.

It appears it will have a 12 hp gain as well...for $1598...I'm sold.

so if getting a turbo back exhaust raises the boost......lets say you put the turbo back on your car and your boost goes +2.....but then after you install the proceed or exceed or w/e and dat raises your boost for ex. +4.....would the end result be +6 or just +4? sorry i know its kind of confusing
