cheapest headers

[rel3rd]

What about the resonators that come with them, that change the sound?

Honestly, I do not think so. They look like mini mufflers when you look inside of them, but I don't think that there's enough internal holes for any exhaust note (or flow) to actually be changed by them...if that makes sense?
Unfortunately, I don't think I ever got any pics of the inside of them.

FWIW, the more I think about it, I don't think they even get anywhere near as hot as the pipes around them do.

Check out the pics I attached. You can clearly see the pipes are discolored, but the shell of the resonator appears like it's barely touched by heat.

The resonators probably do make a difference. If you were to remove them you'd probably notice some time of drone or whistle that wasn't there before. I would leave them on because they do not inhibit flow.

As for the discoloration it's probably because the resonator has a wider diameter than the rest of the piping. Which means that there is more metal to distribute the heat and results in less discoloration.

They appear to be quality built headers and you can't really screw up long tube design.

Cheapest long tube headers

I finally got my pacesetters from car-parts-somethin-or-other out of Chicago. Took them 10 days to ship them 450 miles.

I wish I'd paid the $20 shipping and got them from Texas Speed.

After reading the link to rel3rd's thread I kinda wish I'd just bought the ebay ones..

No intention of removing mine.
I wonder if the resonators are enough of a restriction to allow using the rear O2's to eliminate the Check Engine light? Theoretically, they should.

I'm definitely please with their fitment and quality, and I'd guess you were right about why the resonators themselves aren't discolored...your theory makes sense.
