Corksport Power Series Exhaust

[TheJackyl]

I was going to be ordering this soon however, I was wondering if this would be a worthy purchase or not. It eliminates the second cat and I thought that would cause backpressure unless you have a turbo. I have a 03 pro wit an injen replica intake thats it for power.

also sidenote question, anyone know how much it would be to get springs put on by a shop? I bought springs from another person on this site but need to get them put on. Friend will do it however I have no place to do it at. My apartment complex doesn't allow people to be working on their cars in any way.

That ~250 miles from me. If willing to drive I could help you.
I have heard spring installs for $100? Call around I suppose to all the shops and ask. I went thru this and most of the big shops wouldnt touch it. Ended up doing it myself in my brothers shop at his house. Then finding a place to get an alignment was no fun either.

No idea about the exhaust. sorry.

Ya I'm going to be calling around at some shops here and see. It just sucks caz my friend can put them on its just dont have the place but if i cant find anytihng I will definitely keep that in mind thanks man for the offer

i did my springs myself and it was a lot of fun. took about 2 hours and i guess it was easyier for me becuase i work at a shop

ok i know this is off the topic of this thread but would you guys think A AEM/injen replica CAI be worth it? cuz i know the real ones can produce a "sonic charger" effect because of the way the sound resonates though the intake.

[TheJackyl]

i have an injen replica intake, cant really tell the difference between those that have the real one an mine besides the injen badge

[TheJackyl]

so does anyone know about the exhaust?

[zerocover]

There is no such thing as not enough back pressure, the lower the back pressure the more power the car will make.

The reson cars lose power with new exhausts is becuase the pipe is too big and it decreses the exhaust velocity. That is bad. Removing thte cat will increse the exhaust velocity so that you will always gain power.

[Vash00es]

You NEED some backpressure, otherwise your gonna burn your valves to ****

wouldnt moving spent heat energy away from the valves help cool them better though?

[TheJackyl]

so this corksport exhaust would be a good buy then?

and does anyone know where i can find the OBX/Forza Header at????????

I've got it installed on my 2003 ES, and my only other engine mod is the AEM SRI. Quite a noticable increase in power, especially at mid to high end RPMs. Only complaint is the slight exhaust rattle i get (need to order Kartboy hangers) and the finicking with the hanger brackets on the rearmost part to get it off my rear skirt. I hear its a 10 whp gain for n/a cars, and 13 whp on turbo'd ones.

was this easy to install and how long did it take to get to you after you ordered it? im jus leary on ordering things online

[bigwoo23]

The install itself took about 2 1/2-3 hours. Only problem i had was they forgot to send me new bolts for the manifold studs, since the stock ones were too short to fit. I ordered mine before Christmas and they didnt have any available, but were quick to tell me when they would have them again. Once the production run was finished it was to my house (MI) in about 5 days. The pieces themselves are very high quality, welds are good, and the install was quite simple.

thanks a lot i cant wait to order mine
