yea i bought my magnaflow from modern performance. they were quick and the exhaust is actually amazing. quiet enuff to hear the blower but loud enuff to love it. not ricey AT all maybe except when the exhaust is cold. well worth the money not to mention the fact that modern performance sells it for a fraction of the price everywhere else sells it. if u want a good exhaust with good gains too buy it and buy it from them

I voted magnaflow because thats what i have but after pondering it a bit i would guess GMPP would be the best.......

Over all you cant beat a custom exhaust, you get exacally what you want and most of the time its cheaper than a premade exhaust. And its cool to not sound like every other guy with a premade cat back and downpipe.

That is way too funny!

I like the sound of the GMPP Sport and touring with the slight nod to the touring.
