I have a hooker aerochamber muffler, It sounds nice when you give it some RPM's but what I would like help with is - How can I make it louder without getting cut outs? Will a highflow cat make any difference too sound? Any suggestions will be greatly appreciated.

 

no cats might make it a bit louder.

 

I want to keep it so it will pass the emmisions test .

 

slp loudmouth. i wouldnt gut the cats either...talk about exhaust fumes..yuck.
