Ive also come across many different types of xpipe designs for the E92. Which one is best in your opinion?? @Davin135
Im currently using stock xpipe which is decatted. Works OK i guess. :hammerhead:
In the real world there is only so much an exhaust can give on, close to stock, n/a cars.
I would rather have a good sounding X-pipe that's 5kw down on power vs a car I don't really love the sound of
Personally, I am using an OEM X-pipe decatted as well, the decat alone netted me 22wkw and 40nm

Cowley built a 63mm Xpipe with 2x high flow resonators - Nice but too much drone.
But drove in a one with a catless xpipe and ACS rear boxes OMG:fencelook:
Goals!
With variations in steel and location of the X unfortunately changes characteristics of the x-pipe. Get cowley to experiment by moving the resonators around and see what gives the least drone, OEM resonators are towards the rear of the x-pipe, maybe start there and move them forward.
I have drone as well but only from 1800 - 2100rpm and the car is hardly ever there so I can live with it
