Okay wizards help me out after getting cought with longtube headers and no cats in california now I have to replace everything back to stock to pass the test at the referree station, so I need some good suggestions to replace my flowmaster muffler because I did not pass the noise test after replacing the exhaust manifolds and cats? hopefully I made sense, thanks.

 

Flowmaster was too loud on stock manifolds and cats? Do you have a leak?

SLP Dual/Dual (aka D/D) is quiet and flows well. You could just put a bullet in the I-pipe. That will take it down a few db.

 

Thats right my flowmaster was too loud according to the tech and I really dont want to spend the money in buying a stock unit besides from what Ive heard Flowmaster is not the best flowing muffler out there.

^ Agree with them, they quiet things down pretty good.
