As an aside, we have a set of GM (HSV) cats that have been specially fabricated to fit the Pace 427 undercar system (will work with LSA, L76 and L98 motors) available to rent in order to pass the IM240 test. They feature a traditional 3 bolt style flange at the outlet side that will fit up to the pipes that pass through the chassis. We went with 2.5" piping for the rest of the system.
You can then get a set of high flow cats made to fit up if you so desire for everyday use.

Thanks for the info. Instead of renting the HSV cats, would you be interested in selling a pair?
Do you anyone that has a set of new Pace LSA headers for sale?
Really appreciate the help Paintwerks.
Cheers
