I absolutely love the sound it makes. I have another friend with a 1971 camaro with a 327 small block race engine running a 2 and 1/2 inch flowmaster exhaust system, i can say that the 94 is a little louder than the 71, but it doesn't get raspy or rattle around. I have to think about if I really want to spend the money to get a GMMG cat back.

anyways i like flowmaster on some of the older muscle cars..but its not for teh 4th gens....IMHO....
Borla is ok....its up there in price like the GMMG too but i guess its a model or somthing
SLP LM should stick to the LS1 engines (believe me i know)
Corsa sounds liek crap to me ....
SLP 2OTL on my SS when it had it was awesome...def a great sound but i wanted louder.....
as for everything else..i can realy tell u too much about them
def GMMG is at the top...but is up there in price to....so my second choice would be to go back to teh 2OTL

I got the 40 series with "delta" flow installed today. It's 3" in and dual 2.5's out. I was pretty suprised that during start and idle, it was actually a little more mellow than the SLP muffler that was on there. For normal driving, it is actually a nicer tone. I can't describe it. The SLP muffler sounded great, but there is something about the Flowmaster that I like better. As far as WOT, well I really don't know. It's been raining all day and, well you guys should know...reallly can't do much with it. I did wind it up a couple of times in 2nd at maybe 50-60% throttle and it did sound nice. I can't tell yet.
There definitely isn't any raspyness to it at all. It does burble when at anything under about 2500 revs and off the throttle, with an occasional pop, but that's what the SLP muffler did also.
By the way, We've got AS&M headers on this More Performance 396 LT1.
Hopefully tomorrow will dry out so I can open it up and see what it sounds/feels like.
So far so good!

On my Hooker LT car, mostly stock anything else the car ran the same with the Flowmaster American Thunder connected as it did thru a cutout. People who say "Flowmaster blows" are just repeating drivel they heard on the 'net. However for a car like your's I'd go with a straight thru muffler like the Ultraflow. At that HP any chambered muffler will cost you HP.

I had a 4" Flowmaster on my 396 and put a 4" Dynomax Ultraflow on...
BIG DIFFERENCE.
Any kind of chambered muffler (90% of the mufflers on the market) is going to rob you of horsepower. Straight up.
Get one with a straight-through design.
The Ultraflow is awesome.

Love the Magnaflow CB. Stainless steel, nice deep sound, and straight through design with no baffle BS.

If you go to Magnaflow and listend to the sound clip of the camaro...pay attention to when it shifts...I hate that sound. Is that what the Dynomax is going to sound like?
Thanks,
Steve
Also, how does the sound compare? This car can't be too loud.
Anyone had any experience with the 30 series mufflers?

SLP states that that system (20TL) fits 95 96 and 97, so i guess it won't fit my 93?

Like i said, I've had the single chamber flowmasters on there for over a year, and they're awesome. There are a couple problems though when its cold. When they're cold they rattle like a bitch, but not til about 4,000, and who in the hell in their right mind is going to rev it 4000 when the engine is cold? (I bet your wondering how i found out... Yeah, i was an idiot, but only once. I learned my lesson.) They do tend to pop on deceleration, but its VERY rare, and only when its a rapid decel for me, like going up a hill in 2nd and having to slow down for some dumb *** truck going 10mph...
But, i'm getting headers installed on thursday or friday, i'll let you know they are as soon as i get them. my gut tells me they're going to rattle out because of the added pressure, but i'll guess i'll find out.
As for comparison, the hideous noise that comes from a Dynomax muffler sucks, my friend has it on his Z and i can't stand that crap. Not nearly as much low tone as the Flowmaster, just more noise, especially in the car. It is louder though, but not the good louder.
