I hope that you can help me. I have a Greddy cat-back and a K&N drop in air filter. I want to put on a Y pipe and some headers, who has the best for the performance and money.

 

as far as y pipes go budget exhaust makes the cheapest for about $160 and to the best of my knowledge no one makes headers for a maxima...performance wise the y pipe will be the best thing you could do other then a turbo, and from my understanding the diferent brands of pipes do pretty much the same thing
