What do you uys think about borla muffs being put on or the chambered muffs from www.summitracing.com ?
Ok, everyone says that Flowmaster doesnt flow. Who has proof? A race is not proof. You have too many variables there. And I am talking about the 80 series crossflow muffler, not the 40 series, as they sound down right awesome. I agree that the 80 series is quiet, but all I hear are opinions, no actual evidence that the Flowmaster sucks. Until there is proof, it'll be an urban legend.....

Why can't it be a fact? Because there are plenty of catbacks that will perform just as good (or possibily better) than GMMG, plenty of other high quality systems, and other aspects such as sound & appearance are STRICTLY opinion.
I just don't buy the fact that GMMG can outflow such systems as.....
-Random Tech
-SLP LM
-SLP 2OTL (two on the left)
-Magnaflow
.....just to name a few. GMMG might be close or even equal, but I just don't see it exceeding the above systems by any sort of signifigant margin. Those systems all use 3" I pipes and have strait through muffler designs.

GMMG has to be the best because it costs the most. DUH!
It's all a matter of opinion. I think the performance differences are negligible. I went with GMMG because, in my opinion, nothing sounds better. It's CLEAN and MEAN.

I know it's way expensive. The only way I got one was during a group purchase, GMMG was accepting paypal. I had just gotten a new credit card with 0% on purchases for over a year. So my GMMG is on a monthly payment plan.

Personally, I've had a lot of catbacks on my 3 different LS1 cars, including:
1) Flowmaster American Thunder
2) Magnaflow (the original style muffler)
3) SLP 2OTL
4) SLP dual/dual
5) Bassani Street Competition
Plus many, many other systems that I have either installed on friends' cars or heard/seen sound/power results on. Some of these systems include:
1) Random Tech
2) SLP Loudmouth
3) GMMG
4) Hooker
5) Corsa
6) B&B Triflow
7) Mufflex using both Flowmaster & Spintech mufflers
All around, my top 3 favorites have been the Bassani, SLP 2OTL, and GMMG. Sound, quality, and power being the catigories; these are my favorites. To call any system the "best" just can't be correct, IMO. Too many variables to consider (especially price), and it's just too subjective.

LOL, I got the sarcasm in your post..... it was the quote from my original reply that I was still referring too.

I love corsaIt's expensive but i definitely do not regret spending the $750 for it. And IMO their tips are 1000x better than any other tip i have ever seen.

If you want to modify your car and increase performance get a catback with full 3" mandrel pipe all the way to the muffler so that ls1 can breath.

the 40 series mufflers (like they use for the American Thunder catbacks on mustangs) they okay. Nothing to jump for joy about. an 80 series muffler is simply 2 40 series mufflers stacked side by side. I couldn't imagine ther enot being a loss in power.
and whoever it was who said that races aren't proof, you got it backwards. Dynos are for tuning purposes and bench racers, i could careless how much power one puts down with their mods, what i wanna see is how well that puppy runs, with YOUR foot on the gas. Thats where it does in fact count. completely.
Id get a flowmaster myself just cause I miss that tone. (its a little deeper than my hooker catback), but id never get one without a cutout or two installed.
My knowledge of flowmaster is limited to Mustangs as i came from the Mustang world (shhh no flaming here i moved from the dark side), and even they will explain flowmaster catbacks aren't that great performance wise.

do you see chambers and chambers?
a box of baffles for a muffler?
no.
you see straight through because it does not restrict flow and back up the system. anyone NOT see the ad of the inside of a blowmaster? its FAR from straight through. its a maze for exhaust gases. sure it sounds okay, but that doesnt mean its helping out flow.
who uses flowmaster?
people who bought the "scavenging" pretext from the scam artist at the exhaust shop. people with "street rods". low riders.
the flowmaster is as much of an urban legend
as is the automatic having less potential than manual.
its your cash, kid.

Granted I should have said cheap/crappy, RT isn't bad flow wise just alum tubing and cheap material. The others are stainless and very quality products.
The 1-chamber race mufflers are hard to beat in my opinion. The sound speaks enough for itself. I had a 80 series replacement muffler on my 98 T/A and couldn't tell any performance difference in it. It wasn't really a whole lot louder than stock, but had a pretty good tone. The one chamber's and 3" true duals on my 02 Z, now that's a different ballgame, or really a whole different sport.
Pretty much the rule of thumb with flow's is. If you have true duals yes there "o.k."
The only thing I would run them on would be a mustang or a old muscle car. You can't beat a 1 chamber flows on let's say a 69 camaro with header's dumped at the axle with a cammed small block. Now that's pure music.

I like my borla, nothing like an expensive *** cutout to turn heads...lol Really though with different plates you can make it sound really good and open it up when you want unrestricted flow. Can't beat the $150 I paid for it either..
