so heres the deal. i need to keep my car "smog legal". i already have a SLP lm1 cat-back. here are my two options to keep it legal. 1) get LT headers and a shorty cated mid pipe, OR 2) keep stock exhaust manifold and just get o/r x-pipe.

which one would be louder, and which one would give me the most power.

hows a o/r x pipe make it legal? it shouldn't do that. i say long tubes and catted X... it will sound damn good.

Good luck passing with those two options...

yea the long tubes and cats may not pass in CA but should pass in all other states.
