Hello my name is Ivan, I open this consultation because I would like to know who exhaust could get more power in my rx8, because I have a cold air intake of hks and also I removed the catalyst to put a racepipe tailor-made that works to perfection, but I would like to get a new exhaust and I would like to know with whom I can win more hp.

I come from barcelona,spain and my English is very bad
Sorry

The simple answer is that none of them get you any more than a couple of HP.
Check through the after market exhaust thread

You have to decide how loud you want your exhaust to be. Without a cat converter most of the after market pipes are very loud.

 

Not much power from a catback, maybe 5hp on a good day.

If you've removed the cat, a Borla will sound good.

First of all I want to thank your answers, that the gain in hp is not much, but apart from knowing how many hp could win, I would like to know also, which may notice something over and over acelercion response to low and medium rpm

 

You will not get any more HP than what you have already done to your RX8.

The only gain you can get now is from a CAT BACK muffler system in the back.

You may pick up 3.5hp with the Racing Beat.
