Make 00 MUstang GT LOUD

SLP loudmouth or Magnaflow Magnapacks.

get an off-road(catless) x pipe, I personally recommend Magnaflow Magnapacks. That combined with the x pipe will shake the ground!!!!

You have to remember that you have 4 cats muffling your sound. I think you'll be pleasantly surprised (along with your wallet) if you just buy a $109 Mac o/r H and pair it up with your current catback.

I would think that the Macs that you have with an off-road H-pipe would suffice to scare small children and make old people crap themselves.

SLP loudmouth. NUFF said.

Although the SLP loudmouth....might get to be annoying loud....2 cents

Yo man i got Magnaflows on my car. As you can see from my name its an 88 GT so thats a 5.0L. personally i dont think they are loud so im gonna put some glass packs on it (cherry bombs). Pesronally i think that flowmasters are the loudest ive herd that didnt sound like crap.

i have a audio clip of both back to back packs vs slp.. email if want it 00gt@cox.net

i have the MAC o/r h with the MAC catback and it sounds great, nice and loud. It has a nice throaty sound, unlike the sound of SLP and the magnapacks which in my opinion is just loud for the sake of being loud and it gets annopying after a while.i also have had the flowmasters on a previous stang, and the MAC is twice as loud and flows much better as well. i think oyu should keep the catback oyu got and just get the o/r H.

I have SLP and It's really loud..I have the matching xpipe though..
Magnapacks are loud too...

listen to my car. See sig for exhaust, and video -

Only get Magnapacks, and dump them if you must. That will be loud, and sound beautilful. Sounds like my car, only much louder. No rasp, or funky exhaust notes, or noises that people have, and aren't sure if they really like, but say they do to defend what they have - I'd get BBK LT, and o/r X to do it again though b/c of a small exhaust leak in my, and the Hooker design's slip fit section of the primaries on the drivers side.
