Loudest and Best Catback System

Just bought a 2003 GT and was wondering what the best sounding and loudest catback system out there was? All replies are appreciated! Videos would be awesome too :-D

Any reason an H instead of an X?

H pipes are less raspy and more throaty than x pipes. They have better tones to the exhaust sound. X pipes might gain a few hp, and possibly a couple decibels but don't sound as good.

This right here

Another option is a prochamber, but not sure how it compares to a h pipe in terms of decibels. Probably a bit quieter, but it's so hard to beat the sound. I have a prochamber on my bullitt with a flowmaster catback. Don't remember what the system was called but it has 50 series mufflers I think. Whole setup isn't super loud, but sounds great. Loud enough it's definitely audible at a distance, but not loud enough I have to worry about LEO's hassling me and can give it a little gas here and there.

Hey 13,

I'm going to have to agree with most in here! The Magnaflow MagnaPack Catback Exhaust sounds great on these cars especially when paired with something like the MAC Off-road Pro Chamber Mid-Pipe.

Hope this helps and let me know if you have any questions!

Catted Mid with SLP LM1 or O/R with LM2. UPR O/R X with Mac cat back.

I run a Pypes off-road X-pipe with a 3" MAC catback and I love it.

Heres a stock H-pipe with cat deletes and dynomax 12in bullets welded in place of stock mufflers. Mines a cobra, but it would sound similar. Its way louder than the vid makes it seem.
