put all the info in one post

and for your question pace setter headers suck from what many people on the board have said.... the best for your money would be the RB system (racing beat collected header) if you are going to merge the pipes.... and for the setup you have... its loud especially in my vert... i have the

rb collected header - test pipe - stock mufflers

the stock y pipe sucks as well as the mufflers because they are so restrictive, the sound however is decent but ricey as hell when you get up in the high rpms because thats just how a rotary sounds with the stock muff on it... however i love the sound of it in general but remember its a bit loud and once you get performance straight thru mufflers its gonna be REALLY loud

The most bang for your buck will be the pacesetter header. I ran one for over two years on my streetported n/a, it physically held up fine. Would I buy it again? Nope. Save up some more money, and get the Racing Beat header and presilencer.

Oh and it will add more power than most any other modification you can make on a non-turbo.

During tuning on the dyno we managed 7 peak HP by installing a Racing Beat header W/midpipe attachment. This after the fact of intake modifaction (89-91 Lower, middle and upper manifolds on an S4 block), current exhaust setup (Borla catbacks) and my LT-8 set-up.

Last tested/tuned Dyno run we achieved 173 rwhp from a stockported engine.

Hope that info helps

Yep, this sounds pretty accurate, and why I recommend a down pipe instead (around a 5 peak HP increase) for non-turbos.

But a down pipe is much easier to pass emissions, and is considerably quieter. In addition, my own testing seems that headers help upper RPM HP, but don't do much at all for torque.

I only recommend a header on a non turbo when using true duals all the front to back.

He has already removed emissions from his car, so that really doesn't come into play for his decision. The header vs. downpipe argument is really dependent on which muffler you have. With my RB catback and RB header, it isn't loud at ALL.

I think the RB mufflers are actually really good noise wise. I've heard a couple videos of them and they don't sound ricy or loud at all, just a nice deep reving noise, it was great. Although these were on turbo apps, I think the N/A would sound much different.
i was thinking of shelling out the 200$ for the RB header, but if its gonna make my car any louder than it already is, I'll wait till next spring. The worst thing ever is having a loud loud assed car in the middle of tuning while your neighbors are all really bitchy

I would like to run a header too. My exhaust is straight piped (2.5") all the way back to a single high flow muffler. I'll have to cut and relocate the flange on the bonez straight pipe. So i'm curious also as to if a header would make a difference. I'd defintitly go RB because you can't go wrong with anything RB. If its like 5-10hp with a little wieght savings then I'll go for it.

Agreed.. Especially with tuning a loud car!! But the Racing beat system is a very high quality exhaust. My friend has it installed on his TII and it is very quiet and mellow at all rpm range. I know most people, when they buy an exhaust system, is looking for sound, and wants attention drawn to the car (i know because i did the same thing).

But after driving an RX-7 with a RB Header to a 2.5" single exhaust, and then switching to a 2.5" dual magnaflow setup, I'm straight up sick and tired of how loud it is. It was cool at first, and well it is sorta still cool , It attracts unneeded attention (cops), and its hard to even hear the radio at point.

On the other hand, the Racing Beat header gives a much noticable power increase at all aspects of the RPM range.
I wouldn't reccomend running the RB header, or the Pacesetter header, with the stock exhaust system... It sounds gross IMO.

Overall, i'd stick with the pacesetter since it is cheap, but in the future i would save up and get a full RB system..

Take care, and good luck,
Justin

thats what i am planning on doing i just got my pacesetters in on friday and i am just waiting for the test pipe to fire her up. i dont think that the y pipe back is stock. But i am too planing on going rb all the way in the future or TII.

on the pacesetter the welds dont look pretty neather does the black paint job. but as long as it gets the job done for a while ill be happy

just buy them for $30 i doubt you will be disapointed

Werent the pacesetters the one that proved a HP LOSS from installing them on a stock setup?

I saw some 6-month old pacesetters on an RX-7 convertable that was said to be driven only in the dry. The paint had flaked off, and EVERYTHING was rusting.

From the look of the headers, I'd say absalutely no planning goes into them, they just weld some cheep materials together and call it a header. The wide range of cars they provide for seems to only support that idea.

Ive got a Pacesetter on my 89 GTUs. It was on there when i bought the car, so i dont know how old it is. But contrary to popular belief The paint is not flaking off and rusting really bad. It looks fine......mind you, it doesnt look brand new, but it looks exactly like you would expect from a header.

I eventually will be getting the RB Header when i get the spare cash. Anyone have a dyno comparison from the RB header to the Pacesetter? I think that would help everyone...

Dyno's usually aren't cheap and it seems to me that most N/A owners don't have the financial means to fool around doing back to back dyno runs for just a header.

The pacesetter Cat-back is worse than stock, but the header IS NOT. COmpared to the stock exhaust manifold, anything is better almost.
