Corksport Power Series Exhaust
 

I am thinking of ordering the CS Power Series exhaust system but I am wondering if this would be a worthy purchase considering it eliminates the second cat. I heard that this may cause backpressure which isnt good on a non turboed car. Is this true or would this be a good upgrade for me?

less backpressure you mean.

backpressure (or no backpressure) does NOT make power...It's exhaust gas velocity that makes (or breaks) power.

If it's any consolation I have a non turbo protege and I'm buying the CS exhaust.

I also have the CS exhaust and I like it. Better power gain from a header though. (and easier to install)

thanks guys, i dunno where i heard that but ya i plan on ordering the cs exhaust and a header any recomendations for a header to get?

My next upgrade is going to be the Wagner shorty header. I wanna stay legal and don't feel like removing the first cat. There are a lot of people who like the OBX, though.

yeah, the two main choices are based on your emissions preference.

OBX - $230-ish, 4-1 polished stainless steel about 7-10whp (a LOT Of top end pull), removes pre-cat, throws CEL, requies MIL

Wagner SHorty - $285-ish, satinless (iirc), retains pre-cat, 7-10whp gain (more midrange), requires no other modification

don't forget the ractive header for about $200 as well.

oh yeah, and just so you know what you're getting into... removal of second cat, use of small resonator and canister muffler WILL result in a dramatic increase in noise. (and raspiness with the addition of a long-tube header)

forgot the ractive.....i thought it was identical to the froza/obx

Anarchistchiken put on his obx header, mam cat-less midpipe and magnaflow exhaust and it sounded almost identicle to my obx header and ms muffler. I didn't notice much noise difference at all.

there is a GB going on right now for the corksport power series, might want to check it out, over on another protege forum, i'm in on it, can't wait to get it :D...

whas the other forum caz ima be ordering the cs exhaust soon!

so i should go with the wagner header? and not obx? i dont want to throw an cel

you can still go with the obx, just ge a MIL eliminator from Vielster.

the wagner header is a great piece. It's shown to make more on a dyno than the obx but only 2whp more. The wagner unit is also about $85 more. The reason people typically choose it is to keep emissions.

I thought that was with their hiflow downpipe as well.
