i have a 90 accord and everything is running great i just want to add a little horsepower. i added a new custom K&N intake and im wondering what else could be done to help out my gas milage and over all performance. thanks for any suggenstions

 

exhaust headers, large exhaust pipe, turbo muffler or noise can muffler. clear thru cat. but check with your states smog rules.

 

ok thanks. im running platnium plugs right now would it be a good idea to switch to copper

 

platnium are good. copper is old style.

 

im thinking about going with flowmaster cat back exhuast? worth the time and money?

 

good choice. had this on our 90 accord, not as noisy but no back pressure

 

besides new bolt on items. is there any tuning i could do? what about chips? Do they make one for my car and if so does it really make a huge difference?

 

they make one for the car, but from a lot of replys, it does not make it faster or more power to notice, and it does put your engine light on. we had one from e-bay could not tell the difference. exhaust with headers back and intake makes the biggest difference. You can change your alternator pulley and crank shaft pulley. Then if money permits Nos.
