i just put a skunk 2 high flow cat system and an ingen cold air intake in my 2000 integra ls. the only shitty thing is that iit is an automatic. i dont really wanna mess around with convertining it to a manual. i heard shift kits are a pretty decent upgrade i was just wondering where i can find one and what is the best one for my car.

and also any other suggestions on what i can do to my car to make it a little quicker.
