LN2 Headers
Saturday, September 29, 2007 8:41 PM
Ive been searching, and from what i can tell Pacesetter headers are garbage. Where can i find Something Else? I plan on doing 2.5 back, high flow cat, glass pack resonator, and flow master Muffler. This, and roller rockers, and getting a P&P done, is what im saving for, and im looking for the best prices on good products.

Well i am waiting on my header to arrive, I currently have a megan racing catback exhaust on my car and I love the sound of it. I'm sure that you wont like the look of a can style muffler out the back but man does it sound good.

To be honest, sound isn't important to me. I want more gains....as little as they may be......I dont want to be heard from miles away, and i dont want to sound like a ricer. Other than that..... Im game for anything.

Doesn't OBX Racing make a decent header? I've never used the product personally, but I'm sure someone here has the OBX headers. Besides, you can't really argue with a limited lifetime warranty and optional ceramic coating, and the price looks right on their web site.

If you get the coated Pacesetter header, Id think youll be ok. Only, the ball-cup joint is a pain. I found that using solid motor mounts permits you to get shorter bolts for the header/downpipe flange and get rid of the springs. I just lined it up and tightened the hell out of it.

I painted my header once the paint burned off, preventing rust. It doesnt leak (thanks to the short bolts, no movement at all), or rust now. For the price, im sure performance is about the same no matter what brand (unless you get 4-2-1 opposed to 4-1 style). Pacesetter was cheap, compared to what else I found, and with a little work im more than happy with it.... Sure itd be easier to slap a more expensive header on there and not worry about it, but for the money saved, a few extra minutes of work was worth it to me.

Im going to have 2.5" piping (from a megan racing cat-back), hi-flo cat, resonator, and a magnaflow muffler. Possibly a dual exit setup, not sure yet.

Ive heard a setup like this before, and it sounded great. Its not loud unless you put youre foot down, and even then its not "ricey" at all.

Performance wise, the popular consensus around here is that 2.5" is the biggest size recommended for n/a applications. Ive got a 2.25" right now, all pacesetter, and its definately more powerful than stock... we'll see what happens with the 2.5" -- cant wait!

2.5" is said to have "more high end power", and 2.25" is said to have more "low end power", from what Ive heard, If the gains are noticeable, i will be surprised. Im thinking about 2.25, nothing is set in stone, you know?

I'm using the PS header with a full 2.25" exhaust, high flow cat, 35" Thrush Magnum Glasspack, mandrel bet tubing (cut and welded myself) and a Dynomax Welded UltraFlo Muffler. The glasspack and muffler are straight through perforated core design, so there is no loss of exhaust gas velocity. It has a deep tone and is slightly louder than stock, but definitely not obnoxiously loud.

The PS (and OBX, I believe) have a 2.25" collector and down pipe, so stepping up to a 2.5" system isn't going to do much except for make the car louder. The exhaust will only flow as much as the narrowest point can flow, in this case the collector and down pipe. An internally stock 2.2L would have a hard time supporting a 2.5" exhaust, the power drops off too much by the time you reach the RPMs that need that size exhaust. A P&Ped head (w/ the +1mm valves), a bigger TB (56mm max N/A), roller rocker conversion and/or cam regrind will get you into the power band that would be supported by a 2.5" system.

If you still want or can support a 2.5" system, I would start with the PS painted header, get a 4-1, 2.5" collector from Stan's Headers or Stahl Headers (don't know what happened to Headers By Ed, not there any more), cut off the PS (pos) collector (it's too short and narrow) just above the collector and weld the new collector on the primaries. You might have to cut the collector and add a section of 2.5" mandrel bent tubing to get it to go under the oil pan. Send the header w/ the new collector out to you favorite coating company and get it ceramic coated and build the 2.5" exhaust system with the parts of your choice(straight through, perforated core recommended).

Im going with 2.25", and probably the OBX Headers, as i found them on Ebay for 200. I'm looking into a high flow cat,Glasspack Resonator, and maybe a dynomax ultra flow muffler. Roller Rockers are next up on my list, but i also saw that they are near impossible to adjust correctly. maybe after christmas, I will pick up a 2200 from the junk yard, Clean it up, P&P and drop it in my cav. Where can i find a bigger throttle body?

Between the Cat and the Muffler.... its a tube that is a bit bigger than your exhaust pipe.....

If you can get a hold of one, the 2.3l HO throttle body fits w/ two bolts. You could also look for someone around you that does machine work and have them bore yours out. I know for a fact RSM sells/sold one (if you wanted a name-brand), but its around $400.

If I do get a Salvage 2200, I will P&P the Head, and get the throttle body bore.

Im going to get some quotes on an install price for the Exhaust, then decide on the roller rockers. Im saving now, and if i sell my 92 Cav, that will pay for some of this.

Does anyone have experience with a 2 1/4 in out high flow cat?

Pacesetter is actually a really good header where did you see that it was crap. If you get the armor coated one it maintains really well. The cheap black painted one flakes but no one has proven that there is a performance loss.

Thats the complaints i heard about the Pace, the flaking, and for the Better ones, i can get the OBX for cheaper, thats all

1. ebay sells good headers
2. flowmasters dont suck they are THE @!#$. and u dont need a vette or camaro to run them. especially when they make 60 series whcih are desgined for sport compacts. you are ignorant

You called something "the @!#$", obviously it must be AMAZING!

Will Pacesetter Headers bolt onto the stock down pipe? I would like to install it myself, as i am planning on piecing together this system over the next month or two and havening it welded and installed when i have the cat, resonator, and muffler purchased.

I'm pretty sure it won't bolt up. I wouldn't recommend putting it on the stock piping though, it would increase back pressure and heat.

On the '98+ 2200s the CAT is welded in place. You'll have to cut the stock down pipe just in front of the CAT and clamp the PS down pipe onto the stock piping. The PS down pipe is 2.25" and is swedged down to fit over the stock exhaust pipe.

The PS header will work just fine with the stock exhaust, you just won't get the full power gain available with the stock exhaust. To get the full gain, you'll need to do a full 2.25" exhaust, including a high flow CAT, resonator/glasspack, muffler and full tubing.

Which is what i plan to do, thanks mad jack, you've been a huge help!

After i see if the Gp works out thats being discussed, i think ill start with exhaust work!
