I have my GTA at a local performance shop who I am having create me another y-pipe for my SLP Tri-Y's, mine is dented beyond repair.

Anyway, currently I have a single 3" CATCO going into the SLP TOTL catback.

Since I am having a custom y-pipe made I wish to instruct them how to replicate the factory N10 dual cat option so that I can have 2 3" CATCO cats before my catback so I have less restriction. I am going to be going back to a ProCharger and want the best flow legally CA possible lol.

Because I am CA it will be scrutinized by the smog ***** so it must be an exact reproduction interms of exactly where they attach to the y-pipe, how far apart they are, length from collector, etc.

Does anyone have the diagram from the factory repair manual they can scan and post?! I know that will do but I've since sold my factory manual!

Thanks!!!!!!!!!!!
