1997 firebird 5.7
gms maf, comp cam, accel injectors, air foil, k&n intake
using a goerlich mandrel bent 3" kit with flowmaster muffler. very first mod to car. sounded great, not to loud but had deep rumble under accel.
the over the axle pipe was very tight and took multiple times to get clearenced. added twin tips to rear.
using bbk headers, very hard to install due to clearence issues, barely got y-pipe to fit, had to clearence frame, sounded a lot better ,deeper tone yet but had other mods done at that time. made the comp cam soud so much better.
added high flow cats and made it even tighter and had to cut and weld pipe connector on pass side to bolt to header

I finally have a sound clip of my setup.. true duals, LTs thru Dynatech split flow ovals and Pypes mini cats...cam specs in my sig.

Something worth noting is that the cam grind will have a huge impact on the exhaust note and sound.

No idea. I immagine compared to Flowmaster, or with any exhaust system if set up well, it might... Check www.ls1sounds.com They might have it.

Just got the car back from the shop TODAY.
MAC mid length headers
Felpro gaskets
MAC Y-Pipe
Car-sound catalytic
GMMG cat back
The exhaust is nothing but deep bass below 2500 rpm, kind of like a purr, and above that it sounds like a pissed off tiger. I can't push it too hard because I'm breaking in the rear and tranny, but even at 1/4 throttle the thing's speed feels outacontrol fast.
*Update 17 AUG 07*
I've had some time to play with the setup now and man is this perfect. Plug access is outstanding, no leaks (knock on wood), unreal sound. The coating MAC did on the headers is holding up, and there's no rust anywhere.
The headers aren't emissions legal but I passed easily with this setup.
*Update 13 NOV 07*
So far I've been complemented many times by many people including a Viper owner, and a LS1 owner w/ mids and cutouts. Still NO issues with any of the exhaust components. Here's an in-car vid:

Got Magnaflow catback, good fitment awesome quality, not too crazy about the sound i know most people love the sound. Headers are shorty Pacesetters which are POS will never buy shorties again and especially Pacesetter shorties heard good things about there long tubes. Rest is just a cutout.

yup, I was thinking the same thing. Looks like we are getting a few good reviews so I stickied it
BTW, here is mine:
355 solid roller (263/270). Hooker 1 3/4" LT's, Custom 3" Y pipe made by Mufflex, thru a 3" Flowmaster A/T cat back.

I will be switching up the exhaust infavor of something with less weight. I am thinking of just hanging some small bullets and dumps but we will see what I can fit under there later. I'll post a vid if I ever get that done.

Stock exhaust, but with the muffler replaced by some 3" pipe. Ghetto and loud but it hurt my low end torque, and my ears:

Nicest exhaust tone I've ever heard, satisfyingly loud and deep on deceleration and loud on acceleration. On the in-car clip, the camera just about picks up the deep "boom" sound between shifts.
Its one of the cheaper systems at $295, its aluminised steel but mine came with 2 x 3 foot long 3" polished stainless slash cut tips. I've had it on for over a year now, the aluminised section is just starting to get some rust spots on it, thats with daily driving in British weather. Best money I ever spent.

Here's the thread of my 3" stainless TDs with an X pipe and a chassis mounted Spohn TA with 2 DS loops...The exhaust now exits out the side just behind the doors...The pipes come out of the mufflers and curve back towards the front of the car and out of the sides...The sound is amazing and actually not too bad inside the car, no drone, etc...The Edelbrock 304 SDTs are awesome...I promise to figure out my wife's camers for a sound clip...
At the track I picked up a negligible amount of mph (.25) over my previous Open Borla cat back, but it was about 30 degrees hotter when we tested the TDs...

As in sig ... all MAC pieces using the unbranded copper gaskets that came with them. Excellent plug access. I've had no leaks. A precautionary slight retightening at ~ 500 miles ... still tight ~ 2000 miles later. Sound ... louder and deeper than stock but not so loud as to be a radio or conversation problem at highway speeds. Fairly loud at wot above 4k. The joints are almost all ball & socket (1 slip connection in middle of I-pipe ... to allow slight length adjustment?) so there is easy alignment adjustibility. I was able to use the factory mounting hanger at the rear of the transmission too. It didn't need any O2 sensor extensions but a couple of tie-wraps as wire leashes were used. I'm still using the factory plug wires with no problems.
