Magnaflow Exhaust

Alright i have a magnaflow muffler on the bird right now. Its not true duals.

The car is not as loud as i would like it to be. In fact it is just a little louder than stock. I also have the original cat on it. Would that make it immensely quieter?

What are my options?

Re: Magnaflow Exhaust

Which magnaflow did you use?Stock manifolds or headers?I`ve heard a cat does tone it done a little but all of the thirdgens I`ve owned didnt have cats when I bought them,so I wouldnt know.I have a flowmaster 80 on right now that I think is too loud.I just removed another flowmaster that was a larger muffler with 3"in and dual 3"outs with turn downs tucked up behind the bumper that was even louder.Some people said they liked it but it was too loud for me.I `m` going with a magnaflow next.

Re: Magnaflow Exhaust

ha, mine was really quiet when i got it also. ALLLLL stock and i mean everything. so i was like wtf it sure i quiet. then i said hey, why is it so quiet man? (to the guy that worked at the muff shop) and hes like oh they tend to get nastier as you go along. this was true tho and i drove it more and more it got a little better and better and now even with the shitt 305 it sounds good man. i mean, i actually stood behind it during a rev and an actual drive off and i was REALLY impressed. so keep driving it and see what ya think. oh yea the guy also told me "if you dont like it man, come back and we can switch it out for a flow disaster for free"......i never went back......

Yeah same deal with my dynomax muffler. My piping is stock plus cat removed and it sounded fairly quiet when I had it installed. Drove around for a few months after that. After I fired the car up last week for the first time this year, it sounds much louder than when it was installed.

The 80 is "too loud"? Geez....I think that is the quietest one you can even get. You'd HATE a 40 series!

My Magnaflow bullet muffler is quiet at cruise & part throttle, but sure wakes up at WOT!

Here's a link to my various videos of my exhaust....

This is my favorite video, shhowing the exhaust. The music was added after the video, but it gives you a good idea of the exhaust note.
