Yea that ecu thing is junk.

A header will increase HP like 2 or 3 hp if that. Just try heating your O2 sensor up with a torch and taking it out that way.

torch, or hacksaw it off but a new one...then weld/cold weld it back in

[tengys]

So, how if i just change my whole pipe....and make a custom pipe like 2.25" pipe.....whole exhaust plus magnaflow 5" round ss street muffler.....will it be better than that ebay item???

[Rjb23]

Nope, you don't really get that much HP from an exhaust and header.

[d3monc3lica]

the only real way an exhaust can make a diff. is if your going turbo or supercharged and u need to get the pressure outta there.

icic...thanks anyway.....

woo wooo don't listen to them.....EXHAUST makes a NOTICABLE difference on an NA car not as much as a turbo dur but it does get one its a good thing to have just not 5" tip lol WAAAY too big find a nice 3-3.5" tip thats a muffler at least 20" long

[Kwanza26]

tip size doesn't really affect anything. What's important in a performance muffler is a straight-flow design and the inlet size. The overall length of the canister determines sound, pitch, volume, etc. It does make a small difference in an N/A car... but it's minimal.

i could feel a significant difference in mine and i was talking about tip because of RICE

[creis]

I have a 5" tip, it makes no diff performance wise (obviously) but does give a nice deep tone (little rice but not bad, I like it) I dont know the kinda gains you would get from our cars but headers in general can give huge gains, all depends on everything else, a nice header and stock cat cov. and back will not get you much, but if you have to replace the header I would go for it, if you plan on fixing it up anyway.

I had that same problem when I did my exhaust on my civic, the 02 sen. did nto budge, the only thing i could get to work was to clamp it down in the vice and give it he77 for a wile, it broke loose and came off.

wow!!! after i install the new custom 2.25" pipe (take out the convertor) with the 5"body 4" tip ss magnaflow muffler....it's really increase some performance, feel tigh and more smooth when hit the gas....especially the pickup at 4th and 5th gear....really feel different.....now i can feel the car more strong than last time.....sound wise....is deep......not too loud.....just as good as what i want....very happy with the result....
