Just a couple more pics of it. The collector will be a pain in the **** though.

 

Are you changing it to a 4-2-1?

why did u want to modify it?

 

Will this be remaining a 4-1? Long-tube, or stock length (pics seem to indicate stock length 4-1)? I ask because it would be interesting to see what a long-tube 4-1 would look like (e.g. how gradual the 4-1 merge would be, ideal tubing lengths, etc.) Then again, it would also be interesting to see this somehow become a 4-2-1.

That header with the JDM upper heat shield = sleeper!

nice

 

Is that to make it hybrid 4-1?

 

Wow, that's neat. How do you know what is going to yeild horsepower gains? Do you do everything in a CAD type program first, then build it? Or do you just kind of play it by ear and tweak your designs?

Eli - Who can't even fathom building a header

 

whats the next step, Run two tubes down half the length of the car and then into one?
