I need some advice or suggestion as to what type of header to get for my car. I'd like to get the full advantage of my street port and I think the stock manifold is just too restrictive.

I have the Greddy Power Extreme exhaust (melon launchers) with the Bonez high flow cat. Has anyone tied this system in with a header? I was looking at the Racing Beat or the Pacesetter. I'm hoping to get something that I can just weld a flange to my system before the pre silencer so length is a consideration.

Would adding the header give me a noticeable increase in power or should I be looking at the true dual setup?

 

If youve got the money get the RB header/presilencer. If you just get the header, your car will be really loud and you probably wont like it, so I presilencer is awesome. A header will add atleast 10-15hp on a streetported n/a with mods.

 

Is the Racing Beat pre silencer going to make that much less noise compared to just using the Greddy one in the system? I was going to try and use what I all ready have and hopefully still pass GA Emissions. (Maybe hoping for too much there)

 

The only reason I was going to use the existing set up was in hopes of passing emissions and not having to change out the entire exhaust once a year. I'd like to have something that I could just slap the cat back in for the GA extortion fee.
If there was a way to easily add a cat to the true duals, for the testing, I think I'd just go that route and sell the big *** Greddy melon canon system. I would think I should be able to lean out enough with the SAFC to pass.

 

You can fab up the header to meet with your Bonez high flow cat. The header would be a few inches short of mating with the converter, so you just need a pipe to fit in there. The cat would probably quiet it down more than a presilencer anyway.
