yeah im runing a single exhaust now... no more duals. and it is a side pipe to boot. i wanted a simple system that flow'd well. i threw in a high flow cat for two reasons.
1) its a big fine from the EPA if your caught without one... $1500 IIRC
2) i think for Autocross's you need to have one.
also i dont like all that sutt that you see building up on the side or bumper of a car that is running no cat.
once the mech pulled my factory cat, i took a good look at it... it is pretty good. its a straight thru design. i expected it to be clogged but even after the 160,000 miles i had on it. you could still see right thru.
i have a little more work left for the exhaust... im gonna drop in another slightly diff muffler to drop the volume a bit... and buy a plug insert for highway trips... and i'm gonna be working on my spare set of exhaust manifolds... porting them out and all.
