Test pipes mated to Axleback!

[Trevor .:R]

Hey guys i have a 2011 m3 anyways i have full RPI race, but i want to get the rasp out of there. Was thinking of taking off the RPI catless X pipe and buying Turner test pipes for the m3, but still run the rear section. Has anyone done this? also it seems as most exhaust are deeper and sound cleaner with the Rear section on and only a primary cat delete. Thanks in advance!

buy 2 resonators; it will take 95% rasp away and sound great

if you ever decide to sell your RPI catless x pipe, consider it sold. Shoot me a PM.
