Re: Pacesetter Header-opinion
If you're saving money and it's just a trail rig, then the Pacesetter would do you just fine IMHO. Glenns works real well from what I've seen, and he's right about the savings.
If you decide to go the distance and get a higher end header, I suggest the Calmini over the Thorley. The Thorley uses round tube welded to a square hole flange to match to the exhaust ports. This is bad for flow. Calmini flares the ends of the tubes to become retangle, matching the exhaust port of the 1.3 head. Being an old VW head, correct porting of exhaust headers is important to get every little bit out of small motors.
Calmini also installs the O2 sensor in the collector, where all 4 cylinders can be read. Thorley installs it on a tube so it only reads one cylinder. Not good for getting correct 02 readings.
Thorley has "smog cert", but it was grandfathered in and never had to actually pass the testing, so I'm told. Calmini is still waiting for approval on thiers. But we out here don't need no smog certs, so the point is kinda moot.
From an visual standpoint, the Thorley has nickle chrome, the Calmini has alumicoat. Alumicoat is what you see on really expensive headers and is really impervious to various goo. The nickle chrome looks cool at first, but will discolor and such like motorcycle exhausts over time, especially in our neck of the woods with the road salt.
Just want to give you some facts, rather than hype.
