[99nbmfbird]

I have a 1999 3.8 firebird and want to replace the muffler. Im not positive whether i want to go with the flowmaster 40 series or 80 series. Also, can somone tell me if my stock exhaust is 2.25 at the muffler to 2.5 tips or 2.5 all around. any comments will be greatly appreciated.

Get a magnaflow or borla. Flomasters sound crappy.

Actually most people will agree that flowmaster is the best sounding muffler on the market. Its the only muffler that i know of that actually tunes the exhaust for a spacific sound. Most other (performance) mufflers just flow freer and let more combustion sound through (along with rasp. Borla exhaust systems are overpriced. When you buy Borla you pay for the name (and pretty shininess). But i know how u guys like to put peoples used crap on your cars so you can probibly find an old rusty one on ebay for the same price as a bran new Flowmaster or Magnaflow.

I can vouch for the flowmaster. I just got my 2.5 cat back installed last night and at first I left the resonator out --> raspy as all get out. I then installed the I-pipe with resonator rasp bye bye. at a stop light a ricer asked me "hey man, LS or LT?" I was like uhhh this is a v6. he goes "damn dude that sounds niice". You can get the whole catback from sdpc2000 for 262 dollars + shipping.

dude flomaster sounds like ***.

Borlas sound the best, they have adjustable plates.

power to borla! ...though i haven't installed mine yet..it's in my trunk. hopefully will get it on tomorrow. i've heard sound clips though and i agree magnaflow and borla sound the best.

Re: 1999 firebird flowmaster muffler?????

sorry guys but im still pretty convinced on a flowmaster muffler, the whole reason im only putting on a muffler is because i have no money and i dont want to wait until next year to get an exhaust. i dont plan on leaving it like this forever i will get a nice catback to put on but for right now i just want a little more sound and from whati have heard personally that is the cheapest best way to go. NOW, DOES ANYONE KNOW WHERE I CAN FIND ONE FOR MY CAR?????

i have it and it does take a good two or three months for the sound to get better but i love it, have stock on the rest of all my exhaust components.
