Looks like they're one of the few options for the 20R in the Celica (the other one would be a Doug Thorley 4-2-1 for > $500). They're 4-1 with all the downsides that brings but otherwise seem to be OK-ish.

Put one on a neon years ago , easy and seemed to work well.Was still going strong when I sold the car a few years later. Paul B

Typically they perform well, sound like dookie, some fitment issues, and it is commonly aluminium steel so you will want to keep a can of high temp paint around for touch ups. On the mazda KLDE they made decent power but sounded like crap...

I have used their cat back, it worked well, sounded like crap, its cheap for a reason...

I know the 22R guys seem to prefer OBX. I haven't bought one yet, but the pictues of the OBX I've seen on CelicaGTS.com look better than the Paceseter. Theres a pretty good thread about the OBX over there. Sorry, for second hand information.

The Thorley look really nice, but I'm with you. More than I plan to spend. You can get a header from LC Engineering too, but again, more than I want to spend.

Well, given that I'm just splashing on a set of rebuildable Mikuni sidedrafts with all the mounting hardware I'd really like to keep the cost of the header down somewhat.

Then again, I might pull the head and find that the engine needs enough work to allow me to save up for a Thorley header...

The 'cheap for a reason' was exactly the reason I figured I'll ask around here.

They seem to make them for a variety of cars that no-one else in their right mind would make a aftermarket header for. What about bending one up yourself?

They OBX isn't any more expensive than the Pacesetter.

I believe we ran a pacesetter on our 77 Rabbit racecar for about a year before it was swapped over to a Turbo Diesel. It seemed to work well and it was half the price of comperable products.

I have pacesetters on my '70 GT6. They've been on the car since the 80s and still fine. On that car they're 6-1 headers so not great for midrange, but I can't afford some 6-3-1's

I've put both chromed and painted Pacesetters on Britmobiles with decent results. FWIW, the chrome ones seemed to be made of better steel than the painted ones. Then I put a set of painted ones on my '83 GTi and those were crap. They split at the seams more than once. As always, YMMV.

I got some on my 72 Fiat (came with them). They've been on for a long time, 4-1, I pulled them cleaned them up and hit them with header paint, can't talk about performance since I have no point of comparison but they're made well enough...

I know on rotaries the merge point had lots of pipe corners sticking into the flow path and the flanges were too thin for longevity. You could clean up the merge and make them survivable.

don't remember the issue... (got it somewhere in a box) but SCC did a test of headers (don't remember the car) and the pacesetters caused a pretty drastic drop in hp and torque.......

For what it is worth...I have had three sets of Pacesetter headers over the years; for a 96 Tacoma, 97 Ford F150, and longtubes for a 99 LS1 Camaro. They were all painted and fit reasonably well. I never had any issues with them as long as I had the vehicles. There are better made headers out there, but I would buy from them again.

ddavidv SuperDork

They were just about the only choice for Fiestas back in the day, and I bought two sets during my Fiesta-phase. They were sturdy, both were chrome with horrible finish, the welds were ugly but effective. Flow? Who knows? Better than a stock manifold but I don't think any engineering whatsoever went into them. I'm pretty certain they were build in Mexico.

Pacesetters have about the worse collectors on the market. They mash the pipes down, stuff them into the collectors, which have no taper.

So when it comes to flow, they are about the worse header design on the market.

That said, they often times flow better than the cast iron lumps many manufacturers call exhaust manifolds.

That having been said, Toyota makes darn good factory exhaust manifolds. Especially with the R-E engine (not the R).

My basic understanding is that pacesetter makes their own designs and build them cheaply here and OBX and SSAutochrome copy the designs of others and manufacture them cheaply in China. Basically the copies are of better designs than pacesetter so you are more likely to get better flow.

Very poor fit on my 1500 Spridget. I had to practically cut them apart and remake them. As stated above , the collector section is poor and welding was shoddy.

Yup. The factory 4-2-1 design on Volvos and Euro Spitfires flows far better than a Pacesetter.

I'd consider a Pacesetter a 'last resort' if there were no other options - and a temporary one at that to be adpated to the existing exhaust.

As far as the OP is concerned, I'd either save up the $500 for the good header, or install the stock manifold until I could.

I've had PS on my F-body with no issues and got them CHEAP. I can tell you the welds looks like E36 M3, I also put a pair on a new GTO and they fit really well. Again, welds where nasty but that car sounded like a angry demon that was going to eat your soul

Well, I've got the stock manifold on it but that doesn't flow too well. But given that I'm after a header for performance reasons, I guess I better save up for the Thorley header or try to find a used one.

We have a Pacesetter on the ZX2 autocrosser because it was one of only two shorties made that retain the ability to run a cat in the stock location (per the rules). The other choice was JBA, which was 3x the price and did not look as 'tuned' as the PS with respect to the primaries. Either way, our goal was to shave weight more than make power with a shortie.

The PS fit fine. The welds were a little sloppy, and we sandblasted the painted finish off and applied our own hi-temp rattlecan paint. It did change the sound of the car...instead of sounding like a typical inline 4, it actually sounds a bit more like a Subaru. I do not mind that, just an observation. I would get a PS again if there was no (better) option at a similar price.

I think my Civic has a Pacesetter header. It is a bit louder then stock but with an otherwise stock exhaust it doesn't sound bad.

Anyone I've ever heard outside of this crowd said they'd cracked the welds on those within a few thousand miles.

They suck! I had a Pacesetter catback for an FC. I didn't even put it on the car due to crappy manufacturing. The welds sucked and where the tubes met, you could barely blow through the pipes because they were blocked off (they didn't cut the pipes at an angle before welding them together)
