My Magnaflow is very quiet with even a Cam. Cats help alot, but the quietest catback is the SLP dual dual.

I have Magnaflow as well on my TD set up with no cats. It is quiet at idle and when at low RPMs but when I get on it, it is a straight through muffler Love em

SLP DD muffler or 2OTL muffler. Both are the same identical muffler that is very quiet with a nice sound to it. Hard to explain, but it's sex.

Are you deaf or something? Never stood behind your car? Running different magnaflows than me?

I have magnafows with 3" TD's dumped and it frightens animals and small children. People say they can hear me coming from blocks away.

Borla muffers are pretty damn quiet. A closed borla catback is comparable to stock sound wise.

magnaflow hands down. at idle it has nice bass, no rasp, at highway speeds there is no drone and its very nice in the cabin, you can carry on a conversation in normal tones. but when you get on it you can hear the car from a mile away (literaly)

Stock catback with a cutout.

Leave it shut when you're cruising and open it up when you wanna run.

If you want a quiet LS1, and don't want to "loose" horsepower...

tighten your exhaust!


..and I care btw, I like to talk to intelligent people.

He added one extra O. Does that really make him unintelligent? And how does your spelling lesson have any bearing on his exhaust?

If you want to educate people, start your own thread and let him ask his questions about exhaust.
