I have on my 07 gt 5spd....Magnaflow X-pipe with high flow cats and flowmaster mufflers. My question is, is there anything i can do to make my car louder with out doing any big major upgrades? I do want to leave the cats on my car!

Easiest and cheapest will be to replace the Flowmasters with SLP Loudmouths.
After that, nex thing would be to add headers.

What about shorties will they add any sound? or what if i went with the magnaflow catback?

shorties are a waste of money IMO. LT are the way to go.

Personally, Im satisfied with flowmasters. But if your looking for loud go with slp. If you looking for cheap and loud, just take it to the local car shop and tell them to run straight pipes from the axle back (in place of your flowmasters)...that should do the trick.

+1 to SLP Loudmouths and +1 to LT headers...I rev'd to 5500 at a stoplight and the Honda S2000 behind me blew away in a torrent of wind and exhaust gasses.

Why are shorties a waste of money? Dont they give a good tourqe? I thought they added sound but i might be wrong.
