sdminus

Just went to fit my new exhaust on my 2000ppp and to my horror there is a center cat as well as a pre cat. now im really unsure if i can fit it. Help will i need a remap after or will it still be ok with just the cat in the down pipe.

You will be fine with just the primary cat in the downpipe. Also, you shouldnt need a re-map as the cat in the downpipe is the most restrictive ( most to be gained ). Which zorst did you go for sdminus?

Cheers Mate. I've got it on now. sounds very nice. Got that flat four purrrrrrr now. Its a Kakimoto zorst 4.5 outlet. got it from power eng.
Was thinking of sticking a panel filter in next. not sure where to go after that and what its gonna entail.
As a stock motor\it ran 250bhp at 14.7 psi. spose it would be good to see what affect this addition has on the over look of things.

Apparently, the 'Green' panal filter is best but only slightly better than the standard one. The air box on subarus is actually quite good. It's not a good idea fitting an induction kit as these can damage the Mass Air Flow sensor, especially on your model year. Plus, to make any use of them, a cold air feed needs to be installed. I recently went back to the standard airbox and filter from a K&N induction kit and it actually feels smoother and seems to have slightly more torque.

Nice one. thats handy to know. good to learn from others who know better. Do you know who makes the green one. What sorta spec is your car if you dont mind me asking
