I was wondering if installing a header and 2" exhaust would give me more HP out of my stock 1.3L? If so what header/exhaust?How about a cam? I have EFI so would I need A chip as well? I need more power without changing engine. Oh, I already put a K&N air filter and didn't notice much difference.Thanks a lot in advance...

Do the 2" exhaust from your manifold back with a new easy flow muffler..Do not get a header , they are more trouble and more noisy than there worth.. I had so much trouble with mine allways leaking top and bottom and finaly cracked after only one month..Good luck.. PS You will notice a better performance with the 2"..

It's all about money!!

Exhaust(yes)
Header(no) loud, not worth the power gains
Cam(yes) good upper rpm gain
Carb(yes) most noticeable power gain

Thats my two cents.

The diffrence between a good and bad driver is how many parts you leave broken on the trail:)

Don't listen to those chumps go buy a good header like a Doug Thorley pretty expensive but totaly worth it. I did the header the 2inch exhaust and the K and N air filter It did'nt make a big difference but I still noticed it.And inless your in Depends it isn't that loud
