Rep Power: 0

Seeing as there is a Rate your Intake and Exhaust, I thought this could be benificial.

Dc Sports 4-2-1 Race Header (ceramic)

Power: 4 ( feels good. Gain mid and top end, but I think I even gained a little low)

Fit: 5 ( They give you everything needed for the install.)

Sound: I onyl have a hks axleback, but it increased the loudness on that by more than I thought it would. Still sounds good though.

Also, this header will throw a cel, but you can make a mechanical o2 sensor that will keep you from throwing one. I've driven mine for about 200 miles and no cel yet.

 
Rep Power: 344

same header, hardly notice any gains, slight noise increase
bottom line - waste of money (same with intake and exhaust)

 
Rep Power: 367

you're talking about the race header that replaces the EX's cat convertor no?

cuz it doesnt seem like it. I would expect the exhaust tone to be increased a good bit since you're removing the cat convertor in the process...

or are you talking about the regular header that just swaps out EX's "short" header..
