I've had the AFE catted headers installed about two months ago. When I first had them installed I had the secondary cat delete with the BMW performance exhaust and it was friggin loud. My first course of action was to have 9-inch resonators installed on the mid pipes, which didn't help much, I then reinstalled the secondary cats, which toned it down to an acceptable level, until about 4,000 RPM. I then purchased the Dinan exhaust system, which helped but I ended up installing a baffle insert in the Y pipe. The increase in low and mid-range power was quite noticeable. Obviously, everyone has a different level of tolerance for noise, but the one thing I can assure you, if you are running with the secondary cat delete and the PE, it will be substantially louder. Have fun! |
Thanks man... Yeah I'm excited to get it, I'm hoping the noise will not bother me. I don't know how AA headers can be tolerable with 2ndary cat delete + PE, wow... I am crossing my fingers that the AFE header+AFE mid pipes will be tolerable enough.. I do have the oem mid-pipes worst case.
