Is their a full catback for a SC300 that bolts on to the Downpipe ( sorry for the turbo terminology ) I believe the RMM is but I'm not sure their is no pic. Anyone know if it is a 3'' exhaust ? B/C I plan to do a turbo swap and I will run a D/P and was wondering how the flow would be.

 

It depends on how much hp you are looking for, as far as the flow
you can make up to 580hp or more. the greddy will flow up to
600rwp.I am not sure about the jic magic.

 

Hmm I was looking for 750RWHP, any thoughts ?
