GMMG, no contest. I havn't dynoed yet, but I've heard that GMMG flows very well. Plus you cannot beat that signature sound.

I think the best sounding car on ls1sounds.com has the mufflex on it.

mufflex with the spintech muffler sounds killer as far as catbacks go. GMMG sounds good of course but not 6-800 dollars good.

If Mufflex used a different (i.e. freer flowing) muffler than Flowmaster or Spintech, I'd choose Mufflex.

GMMG: $700
Mufflex: $600

Only a $100 difference, and that extra $100 goes to GMMG because you can't beat the sound.

Mufflex also sells a system with a single tailpipe for $450. How

guess GM is gay too, considering the 98 SS's had a single tip option.



Mufflex can be had for 500 if you look in the right places. I'm trying to find a good deal on one myself.

They underrated the f-bodies so they could keep sales of the vette up, not to mention killing off our precious fbodies, You decide for yourself.

if you like annoying people and having your car sound like a straightpiped piece of redneck crap pay way to much for the GMMG exhaust, if you like deep rumble and good sounds get Mufflex

if you like the straightpipe sound, just remove muffler, it would sound better than the GMMG or SLP loudmouth. can you tell that i HATE those exhausts?

Either you've never heard GMMG or your jealous. The meet we just had recently out of ALL the fbodies there, everyone agreed that GMMG sounded badass.
