I had that setup with slp catted x and they were loud at 10 in first gear. I had to swap catbacks when I swapped the IRS in.. magnaflow catback ftl, I've since had an exhaust shop weld in my spare lmII's I had under my bed.. LMII's with a catted x doesnt really get loud until about 2k rpm's whereas the lmI's are loud at 1.5k

I'd go with slp LT, catted x (o/r x w/lmI's is nasty sounding), lmI's, and a cam with a huge lobe. Or an o/r x with LMII's.

Honestly, LM1's may yeild the most hp (only by MAYBE 1hp), but to me they sound liek a bunch of tin cans being drug behind a vehicle while someone is clapping... Yeah...

This is my opinion.

Hooker Long Tubes, matching offroad X, Flowmaster 40's or Bassani. Handsdown.

headers+or/x+loud mouth 1's= ultimate exhaust

If you want loud as possible....LM1's. If you want some tone...Bassani or MAC are my favorites.

well, maybe its just personal bias....and dont get me wrong, i like the way the various loudmouth catbacks sound with O/R xpipes....

but to me, with a nice set of chunky stage II cams, the undeniable ultimate mustang sound to me, is Mac Longtubes, Mac O/R Prochamber, Mac Catback. It might not be as loud as the LM's + O/R Xpipe, but believe me, it still screams....

you hear a cammed 4.6 with a prochamber coming, you dont even need to see the car....you KNOW its a mustang. some stangs with Xpipes and LMI/LMII's sound good, but dont sound as definitive if you know what i mean.

and call me crazy, but i think prochamber/mac catback sounds better on 2V's and xpipes/LM's sound better on 4V's.....
