Hello, I own a 95 v6 3.4 camaro. I just got a flowmaster 80 series put on because my old muffler broke and one of the pipes fell of. I dont know whether it was put on wrong or something like that but it sounds really quiet, at idle its pretty silent and at lower rpms it quiet at higher rpms its alittle louder but still nothing like I thought it would be or what people told me it would be ( it sounds no diffrent then like a generic car) and I've also noticed a pretty big decrease in power I'm not sure if it has anything to do with the new muffler or not but acceleration feels diffrent and I'm having a hard time hitting speeds i had no problem hitting before.

 

yea an 80 series flowmaster is supposed to be quiet. look into a 40 series but there is better out there then flowmaster.

 

I agree, Flowmaster is the best. But I have a problem, I cut off my cat. converter and now my Flowmaster sounds it has a broken baffle. Any suggestions.
