Ok I am getting together with a local race shop (drag cars and sprint cars) and building a set of long tubes. I went and started laying out parts need and will post updates for you n/a guys. I bought 2 new o2 sensors and a 2 1/2" high flow cat. Currently looking for mild steel merge colletors. Any of you guys have any or know where to get them for a good price? PM me if you have info.

More updates to come.

Flanges are in. They are pretty damn heavy and this mild stell exhaust system is going to add some weight for sure so should be around stock weight.

Last piece to the puzzle came today! Planning the build next sunday.

Anything else I need to know about before I start and buld these? I hear the primaries need to be over 30 inches to have any effective gain. Anyone else?

Do you have any idea what you're gonna do or are you just slapping some pipes together and callin um headers? not trying to be mean, just wondering if you're working with the race shop or have anything drawn up on how they are gonna look or if you're just wingin it.

According to Burn's Stainless, the primaries should be 30" long,
1.75" od,
1,5/8" id,
with a collecter that is 2.25".
If you have a stock cam.

We have a basic idea and I stole a bunch of pics of other builds so it should go well. I know from talking to svxfiles there were some requirements. This guy builds all sorts of crazy stuff so I trust he knows what he is doing. This setup is not going to have any flanges. It will have a flex pipe before the cat though.

Gasket came in today. I almost forgot about them so it was a last minute order and quick shipping. These are from smallcar.com too.

I almost decided to scrap the project due to the time to build them and the cost of parts and labor. Tomorrow the building begins. I expect it will take a couple of weekends to finish the complete exhaust.

Sweet! Can't wait to see some pics of this going together. Exhaust projects always make me grin.

^^ Haha, same. It's one of the things I always volunteer for at the shop. "Oh, that 'direct fit' aftermarket exhaust doesn't really work? No worries, I'll get the chop saw and welder."
