Gauging interest in custom exhaust manifolds
As you probably know, the factory exhaust manifolds are very restrictive, but building a set of proper long-tubes is very difficult for this car because space is tight around the steering box and the exhaust crosses over to the passenger side under the transmission.
I am talking to Stainless Steel Headers Mfg., Inc about building a set of custom log-style manifolds based on their turbo headers that would follow the factory routing, but have larger diameter piping and flow much better. I'm thinking the setup would be a pair of the manifolds with V-band connections to a pair of custom downpipes that also follow the factory routing and end at the resonator. In theory, it would be a bolt-in solution from the heads to the resonator and would also remove all four cats.
The manifolds would look something like this:
If three or more people are interested, and commit to the purchase, the cost can be dropped significantly. I don't know enough to give a firm price yet, but it sounds like we could get this setup for $2000 or less.
Who's interested, and at what price point would you be willing to commit?

Hiow much do you think it would cost?
I'm not trying to bash your idea just curious. I am trying to keep my M113 stock so because I have other projects but that doesn't suit my personality. Yeah, Kleemans would be nice but we all know what that means. I have a set of headers for a S62 to buy so Supersprint/Evolve may already have my exhaust money for now.
I'm in for the details.

If I had the time, I’d love to get a header kit template from “ice” and mock up a set. Problem is, I don’t have the time and I bought my CLK55 for daily purposes. I told myself I would t go too far with it. We shall see.
