I would not run catless on a street car. Why...the exhaust just sticks to your clothes. The high flow cats from stainless works are tiny and they do a great job. Even if I did not live in an emissions state I would run HF cats because I hate smelling like I just finished working on a B&S motor.

Would these work? It says '06-'14 but should work for +15s, no? Nevermind looks like it is for their headers.

Spool...did you see these? Looks like price dropped 6%...but still ~$400 ($389).


Oh and JBA does make a set...but for more. (6.2/6.4 only)
