Default catted x-pipe w/flowmasters

Ive heard in the past people dont like the sound of the set up with a x-pipe with flowmasters. Let me tell you, Ihave a magnaflow catted x-pipe american thunder cat back on my 04 GT and it sounds really good. Not raspy at all like everyone says the x-pipe sounds. I had the loudmouth 1 and 2 on my car and the sound just wasnt for me. With the flows, totally awesome sound. Had system on car for 2 weeks and had lots of compliments on the way the car sounds. Anyone have an opinion on this kind of set up?

I suggest go with a catted or non catted x-pipe depending where you live (for emissions) . The x-pipe will give you more power than an H pipe. The sound is different depending on your cat-back. H may be a little more deeper, but the X does not sound bad if you have the right set up. Ive had the LM 1 and 2 cat back and both systems were way too high pitched for me. Therefore I went with flowmaster american thunder and was very satisfied. Also shorty headers (ceramic) would be a good move. Shortys are better if you ever need trans work done and give good power gains. All depends on what kind of engine work you have had done. The more internal engine work, the more power gains you will get out of your exhaust system. If you dont plan on heads/ cams etc, then save doing headers for a while.

I have a SLP Catted X on with my Flows and it still sounds good, but I'd rather have my O/R H on which I will probally switch after I go get inspected.

i just got my car inspected in fort worth, and the mechanic told me if i ever were to get an o/r xpipe or anything to go outside the city to a more rural area to get it inspected b/c they only do the safety inspection, no emissions. i just need to find out how far ill have to drive to get that done

X and H pipe are practically identical for power. I read magazine that did intense dyno testing on a 5.0 with both pipes.. the X netted like 1 HP more PEAK ona particular setup, but even still it had less power over most of the band than the H pipe had. In general the H produced a better power band (read: better e.t.'s) than the X.. just SLIGHTLY less PEAK power. Differences were minuscule in either case.

To make any real power gains though you need non-catted... 'high flow' catted pipes will not give near the same performance gain as any offroad pipe will.
