Hi All,

Just wondering if there would be any issues with adding the FI RHFC to my existing motordyne shockwave e370 catback? (On a 2009 G37S coupe)

How much do you think adding these RHFC will change the exhaust note?

 

If you currently have the stock cats on there, the resonated cats will make it louder, and it'll have some deceleration hiss, for sure. You probably won't get rasp on the acceleration, though. Note will probably get deeper, fuller body.

 

its all subjective, but definitely louder
