i have slp lm1's
but thanks for the advise![]()
BurningRubber said:I have the UPR aswell. I cant get it to seal in a certain spot, and am not sure where yet. Aside from that, its great. It was used and sealed perfect on the car before mine, so dont let that change your mind. Its inexpensive and nice. As for sound, I cant comment much cause I have stock mufflers and its not loud enough for me... it makes a unique sound though for sure.
03MaCh1nE said:AS UNIQUE....U MEAN A "A HORRIBLE SOUND"...OR A"DAM I CANT BELIEVE MY CAR SOUNDS THIS GREAT????
03MaCh1nE said:slp is one of the greats but it cost so much...

That doesn't even capture the awful sound it makes. It's so loud and nasty that it'll make you embarassed after a while.![]()
