what pipes are u running with crimson? the cops in my area arent that **** but its the few time that i stepped out the valley and go to other parts of so cal that im worried about

funniest story was when my friend got pulled over for loud exhaust on a stock 350z

and if i do get a test pipe like from UR..which is said to be gauranteed not to get the CEl error, u think its a good set up?

i have the Espelir Cat-back. Before i go catless i want to make sure how smog testing is done here so i don't have to go through a lot of trouble.

No cat+downpipe+Catback= reflash or tune in order to get the most out of it.
