Hi People, OK On Friday I am custom building a stainless exhaust for a sport, and as I build all the silencers up from scratch I was hoping to get a head start in preparing them... would any of you owners out there feel like / already know the config of the the cat back system?

I think the Silencers are 5 inch round x 9 inch long (2off) and the other is 10x5 inch by 18 inch(going from 2inch bore to 2 1/4 inch bore

I can do it all on Friday but I want to make sure the customer gets her car back as soon as poss.... plus its Friday and I fancy a beer after work!

Anyone help!?
