what is better for low-end a midpipe or a hi-flow? If you have a midpipe is there a way to take it out for emissionz?? I like HKS exust, so what is the best they make for the RX-7? I don't care about noise either, actually i like it better. After doing intake, and exust what would be the next step to getting more HP?

 

For low-end power? Hi-flo cats.

As far as the next mod after an intake and exhaust, that would be ECU.

 

Oh, as far as exhaust, are you talking about cat-backs?

If so, most people will probably recommend A'pex N1.. Honestly, it really just depends on what look you want for your car. The performance difference in the cat-backs won't be enough for you to notice.

I'm running the GReddy Power Extreme and like it a lot.
