2nd cat delete, any performance gains?
hey guys,
ive just changed my rear muffler with a remus back box on my 430, i like the sound, nice tone and not loud.
what i wanted to know if there is any performance gains in deleting the secondary cats?
im thinking of replacing it with 2x2.5" >3" Y pipe then 3" to resonator
would there be a loss of torque doing this?
have done search but no real answers.

99CLK320,
ghostrider fabricated an exhaust for his 430 without the 2ndary cats and Williams007 has a a 320 he purchased in Japan and I know he doesn't have primary cats. I would look up/search posts by both those guys.

CLKs in Japan come straight from the MB Factory without any Primary CATs.

im guessing this will cause more of a restriction as the exhaust would be crossing over too many times.
