I was thinking of lining up 2 cats together or do u think i should just put one in.
im runnin a jdm h22 with a hotshot header 2.5 exh no cat with a magnaflow at the end. id figure i would line up 2 of them together right away instead of just doing one because it would save me some time if i werent to pass with 1 cat. and yes the egr and emissions crap is hooked up and working fine. but then i read up on laugHin22CX little deal with him passing emissions and said that with 2 cats it would not heat up. so now im thinkin of just putting in my stock cat and puttin on my oem axle back and leave the header. what do u guys think? heres the post
