SLP dual dual loudmouth

**Bigdaddy** · 11-11-2008, 05:36 PM

Since my longtube install it's too loud. I wanna try something else. Been looking at Magnaflow. Will I lose anything? It's carefully tuned to 345 hp and 360 tq right now. I saw a car on here with a cool looking exhaust a while back that he swore by. Any help guys. When i get something the slp will be up for grabs. Thanx.

dyno's have shown 0 loss in horse between open header and magnaflow muffler (this does not include the extra piping of a cat back system). there are no chambers in magnaflow, no baffles, just sound-absorbing material. magnaflow is a good way to go. borla w/ plate would be same but borla wouldn't be worth the extra money if you werent gonna run it straight through.

I liked the sound clip of it too.

yea it's good soundin'. well i've never heard an ls1 i didnt like. but i know exactly what ya mean about the loudness. i got cats with my dynatech's for that very reason- only thing i have to quiet the car down is the cats. "but side2000, you are an idiot for racin around with cats!" the high flow cats take VERY little horse.....and....i also have an ory..........

I've got an A/R catted y pipe but the cats are the size of a beer can and can't be real restrictive. I'm very happy with my #'s. For now. That was a Mustang dyno too. Next, shift kit and cam. Just have to figure which cam. It's a nonstalled daily right now.
