WOW! 150 CD for mandrel bent cat back is a SUPER deal compared to US costs!

The recommended size for the 1.8L DOHC is 2.25" for manual and 2" for auto.

so...you are saying....with the SOHC i should probubly stick with 2" and not 2.25"... would there be any loss in power with the 2.25? b/c i don' tknow what i'm going to be doing in the next year...and i don't wanna have to redo the exhaust....would 2" be more effective in the SOHC.....anyone kmnow from experience?

BTW.....its a 92 SE SOHC 5 Speed....

Agreed. And when you go turbo you're going to want 2.5" anyways, which is too big for NA, so I wouldn't include future turbo in your exhaust plan.
