SLP Exhaust

go to rpmoutlet.com. click on Mustang GT parts, then SLP exhaust. it will show you the physical differences of how they are made.

i've had both. the LMI's sound great with the stock H. they are loud and pretty raspy with a catted X, and sound like **** with an o/r X.

the II's sound a lot better. still loud but deeper with no rasp. sound great with an off-road X :nice:

alright thanks man. i am looking into buying one and wen i saw that there was two i was confused.:nice:
no problem man. the quality of SLP is great. personally i went through 5 different SLP combo's before finding the one i really like, which is what i have now. like I said the I's are great if you are sticking with the stock H-pipe, but if you plan on going with a catted or o/r X-pipe then get the II's.
