Best performance mod by far is my headers and exhaust. Had a small gain from removing the airbox and using a K&N air filter, no noticeable gain in power but smoother running from a set of MSD plug wires, but nice increase in throttle response and upper rpm power with the doug thorley headers and 2 1/2 inch catback. Still not enough though so the GTE engine goes in next week:icon_evil

Hey guys! I wanted to know some oppinions before I wen't ahead and decided on anything. First off, I am searching the market for an exhaust system, the whole thing. I have my eyes set on 935's 2.5" exhaust system, ( Stainless of course) and I'll more then likely use the muffler I have. As for a cat, I might go magnaflow or something along those lines, but I wan't to know all your oppinions on some headers, and really what works and dosnt!
1) Pacesetter: I've heard good and I've heard bad thing about these. If someone could shead some light on them that would be outstanding!
2) OBX: I have no idea about these so if anyone has info do tell!
3) Jim Hall: These are suppost to be perfect fits, ceramic coated, and port matched. These sound like kickass headers but one problem...where can I get one?
4) Doug Thorley: These look like awesome headers, and I've seen one good post about them. Problem is are they worth the money, and I only found they fit the MKii?
5) PAECO: I know nothing about them.
This is what I found so far. So if any of you know anything about anyone of these share. I need headers...

I think if you are looking for new ones you might have a problem. The set of doug thorleys I have fit my mkiii fine. I did modify the bottom of one of the runners to give better clearance from the ground and the x-member but they fit good. Great upgrade for the NA and although they are hard to find they are probably the best 7M headers out there. I believe they are the same as the TRD headers were. Mine will be for sale soon so look out.......

you guys need to buy an exhaust. I think that a 3" exhaust is perfect for a 3.0l motor. I had a 2.5" exhaust on my NA eclipse (2.0l motor) and the difference was def profound. From my point of view it is more than capable of handling your power needs yet not big enough to hinder performance. What you guys have to remember is that backpressure for any car is bad. What you want is the maximum exhaust gas velocity. But with that exhaust on my eclipse and minimal mods, meaning a intake and upgraded TB, I was able to drop over a second off of my 1/4 mile time (from a 16.57 to a 15.46 and for an NA 2G eclipse that still seems to be a time that is in the top ten ever even though at the time it was the 2nd fastest). Dont be so scared of going bigger than a 2.5" exhaust on your car. You will appreciate it later
