I just had my new Spugen dual Ti exhaust installed and it sounds good just too loud for me, especially inside the cabin top up. I am curious is there anything out there for aftermarket cat/testpipe that will help quite this exhaust down a bit. I've heard some people use the Megan testpipe thanx for the help.

 

You could have a larger resonator welded in rather than the small one that comes from Spugen. A testpipe. even the resonated Megan, will make your exhaust louder but might possibly get rid of some of the drone.

Put the stock exhaust back on.
