i have the bonez full race doen pipe, i was wondering if i can bolt a header up to this down pipe, anyone help?????

My#7

I MENT "DOWN PIPE"

darkwaveboi

no, you cant. The downpipe connects to the stock exhaust manifold. the header connects to the engine block. Wont work.

Im assuming you have an NA, if you dont, then know that turbos dont use headers

My#7

so i need a different downpipe to bolt up to the header?? i know that the header bolts on to the block, my question was from the header to the Down pipe will that work??

I have a 89 N/A by the way

TriTurboGen3 RX-7

By my understanding it goes (with N/A) Header, to Midpipe (racepipe), to Y pipe (if u run duals), to mufflers.

just wondering you can bolt a turbo manifold up to a 13b and a n/a exhaust manifold onto a 13bt right? the bolt pattern and ports are the same(besides the defuser)??

darkwaveboi

i believe they're the same...anyoen got pics of their turbo mani?

You CANT have a header AND a downpipe, a header mates to either a cat converter, or a midpipe. The point of the header is to rid yourself of the pre-cats AND the stock manifold which is more designed to quiet down the car then to give it power.

One could certainly fabricate a turbo header. The gains should be obvious.

I think you are talking about this race pipe, right? Well, you could probably take it to your local exhaust shop and have them cut, and possible bend, your race pipe and weld on a flange so it will mate up to the header.

Or, if you buy an RB header get their presilencer while your at it and save your self a lot of trouble. Those presilencers are built to mate the header to the y-pipe (if you are using dual exhaust).

Dont use the presilencer on the race pipe. My friend did that and it sounded like **** (buzzes.) Just go ahead and buy a header and presilencer combo from racing beat. That presilencer is the best at keeping resonation to a minimum. -Gabe

I believe thats right, thats what i have

I have the Header / Silencer combo from RB,im pleased with it and it gives a really nice sound, i like it anyways, along with N1 Mufflerz

My#7

so i should buy a header and pre-silencer from racing beat and sell the down pipe??

My#7

Header/silencer combo??

My#7

how do i get the header/ down pipe combo????

DEZERTE

well, when i got it, i called up racing beat, and told them i wanted to get "Headers and wanted to replace my cat with a straight pipe" im a noob so they knew what i meant and recommended the Headers and "Presilencer" as they like to call it, i ordered it over the phone from them i also have an 89 NA here is their contact page...
