97SHwhat

searched a little on this but couldn't find what i was looking for.

about to buy the greddy evo2 catback for my 97 sh.

what size CAT should i get, and what brands are decent?

also, should i think about getting a resonator? i'm wanting this to sound good so any advice would be great! thanks guys.

oh and if its loud thats not a problem..as long as it sounds good.

willing to add what it takes to make it sounds as good as it can.

For cats some people like the pricier Random Tech, but to me you will be fine with a carsound/magnaflow. Just make sure to try and match diameters from your collector, cat and exhaust.

Lots of cat, collector, exhaust topics covered here. N/A Performance Library (README!)

i checked there..but i'm stuck because the piping on the exhaust is 2.36. collector is 2.25

obviously i'm going to have to take it to a shop to get it put on the exhaust correctly..but should i just get a 2.25 high flow and make the put it on the piping?

This kinda goes back to the inner diameter outer diameter issue. Most of the time the 2.36 is OD, so the ID is close to 2.25. Just make sure not to bottleneck and you will be fine.

ok, well im guessing 2.25 woulld be straight through and wouldn't bottleneck until i upraded headers. i'll probably go with carsound...seems like with random tech there are alot of CEL codes thrown, and most of em go out after a year??? thats not good.

Solid

Well if you are worried about CELs you should use two anti-foulers to keep the rear O2 out of the cat/test pipe.

So if you get a high flow cat it will throw a cel?

97SHwhat

only some will with obdII...happens everynow and then depending on what cat you get too..i was just saying that it seems to happen more often with random tech (atleast from what i've seen) than others. worst comes to worst i'll just pick up the cel eliminators.

97SHwhat

just incase where would i get the anti-fowlers? installation etc?

Solid

Search my friend

18mm Anti-foulers are sold at Autozone or other parts stores. The rest I will let you search for.
