How much HP?
How much more HP can I get out of a full exhaust? I ordered a header, pre-silencer and catback all from Racing Beat. I was wondering how much HP I will gain. I know that the true dual setup from Mazdatrix ads about 28% more or so. So I am thinking about 20% or so? Also how loud will this system be? Thanks I have a 88 SE.

20% sounds about right. As for the noise, it shouldnt be too bad. The RB mufflers are one of the quietest for the RX7, and with the presilencer, it should sound good. Not too loud, but good.

I have the same kinda questions. I was gunna order just the headers/presilencer combo & get a catback later. I scratched that idea & am gunna wait till I have enough $$$ for the mazdtrix true duals. I like that they dynoed it, makes me feel comfortable about the performance I am paying for. When I get enough money I will let ya know how it goes.
