Euro Header Collector, to weld or not to weld? Options

[jhadler]

Hey all,

My other question... I ahve a European Header that I've been long planning on putting back into the car. It looks like the collector is designed to just bolt up to two of the primaries, and that's it. Is it better to weld the collector to the primaries? Or just clamp it? Welded would prevent any axhaust leaks, but welding would also make it more rigid, and may stress something under thermal expansion. Thoughts? Suggestions?

Reason being is that I'd like to try using a different collector. I'd like to try the Flowmaster scavenger collector, effectively getting me an additional 18" of secondary and making the system a 4-2-1 instead of a 4-1. The class I run in doesn't allow internal engine mods, so I need to go with the strong suit of the engine, and that's mid-range torque.

Thanks again!

Thanks for the info Chris!

Yeah, I do so want those headers, I've wanted a set for a very, very long time. Ever since I wandered by Pete's shop in Palo Alto and saw him working on a set for a customer at the time. But as it stands, the race car only gets a limited budget each year, and right now, it just needs to get -running-.

I knew I wanted a set with stub pipes. So it came down to yours and the Euro headers. I know, I know. You get what you paid for... But I had to make a cost/benefit decision. Get the super headers, and leave the car on jack stands. Then sit in the car and make vroom-vroom noises. Or don't get the best, but get it running, and on the track. Let me tell you, it was a tough decision. Thanks for the info! I'll see about fitting the original collector. Either way, should be a nice gain over the stock heat exchangers...

Chris, what was the result of the appeal from Runoffs? I saw the video clip, and I agree, that guy doesn't belong on the track... I hope the car gets back together without too much difficulty.
