Hello,

i just recently bought a 07 tl type-s and i love it i had a suv before. Im new to the whole modification thing and really do not understand it all. But i was wanting to purchase and redo the full exhaust j pipe back to the exhaust tips. and i was looking at getting
-atlp j pipe
-atlp v2 cat back
and what other peices of the exhaust will i need to replace?
resonator? or a cat-pipe?

and my other question is will any of this set of the check engine light? thanks

 

If you want to stick with ATLP, the only other piece youd need would be an ATLP test pipe to delete the 3rd cat.

This wouldn't throw any CEL's since the 3rd cat does not have a sensor on it.
