    Flowmaster...or NOT

    I recenlty sold my 99 Camaro and bought a 02 Trans AM. I had Flowmasters on my Camaro. I wanted to get an exhaust put on the Firebird. Any suggestions on brand of muffler. I didnt want to go with Flowmaster again...heard they were too restrictive. I don want something too loud but loud enough. Any Suggestions.

    MagnaFlow all the way if your wanting something that's quiet when it needs to be but has a great tone at heavy throttle.

    Being you live in Chicagp like I do, I would get cut-outs after the headers for the performance you can open em up and close them off when you want to use your cat-back. Flowmaster is good for the sound restriction while driving the streets. You know if you go any louder they're gonna pull you over for loud exhaust.

    Magnaflow is real similar to flowmaster I would say its a little meaner sounding though they're about the same price too.

    magnaflow has great flow and volume. If you want to make children cry get SLP loudmouths.

    I got a Magnaflow catback for my 02 SS and really like it, real quality stuff and sounds great. Not too loud in town but nice and mean when I get on it.

    magnaflow, i used to have flowmasters and unless you get like the 40 series your wasting money. the 80 series suck, they dont flow well at all, not much better than stock. magnaflow sounds so much more aggresive as well

    Check out this car: http://www.lsxtune.com/gallery-02.htm

    before tuning, it made 373rwhp with a Flowmaster cat-back. Just after that pull, the exhaust was switched to a Hooker catback and the car (again, same day, same dyno) made 392rwhp. Only change was the catback. The car cracked a little over 400rwhp after some tuning.

    I just put on a Magnaflow Catback last weekend and I love the sound. I don't know the effect on the HP but the tone is great.

    the flowmaster 1 chamber 10 series are not restrictive at all that is about the only one i would go with though the other flowmasters can get pretty restrictive. here is a clip i found he has some others too.
