I went with Flowmaster Delta 50's on my 2003 GT...I have had them for 3 1/2 years with no complaints...They roar when you nail it but are very drivable...My neighbors appreciate them I'm sure...
That is not what I wanted to hear. I don't care about much about small hp increases/decreases. I just want her to be quieter that the MAC Flowpaths on there now. Your saying your Magnaflows are loud? That's not so nice. Maybe I should have went with the Borla Pro XS mufflers.
I ordered a set of Magnaflow Mufflers (#3 on list) part #11236. Waiting to see how they sound installed with a MAC Pro Chamber and MAC catback (now to be a hybrid catback).

FYI - Magnaflows have offset in and out, Magnapacks are literally straight thru.
And is Mac really that loud? If so, I'm definately going with a Mac catback.
Where's SLP? And is Mac really that loud? If so, I'm definately going with a Mac catback.

True, but to clarify... Straight through refers to the fact that there is no redirection of exhaust flow (chamber), or flow through muffling material (like a catalytic converter for example). The way a magnaflow muffler works is it's a pipe (bent or straight doesn't matter, it's still "straight-thru") with HUNDREDS of tiny little holes drilled in it, then that pipe is encased with fiber dampening material, which is then encased in an alloy case (the muffler). Amount of sound dampening depends on size of the muffler and shape of the case.
Magnaflows sound badass, Borla XS sound sick too - never heard the hookers.

what about the Steeda catback? Is it as quiet as Steeda claims?
I want to run the MAC catback with my LT's, but I if I get Germany as my next assignment, this GT is coming with me. I don't know what the noise restrictions are in that case
