I wouldn't convert to a dual exhaust, having the wastegate dump right there is probably most efficient, and will probably sound best

I was joking about the dual exhaust

my God, you're lucky if you get power at 7000rpm with that setup. I dont think you'll get any exhaust flow with that monster piping. Too big is gonna hurt the exhaust current flow-there simply may be none. Good luck anyways, its definetely the wildest Ive ever seen!

Now we want to hurry up and finish it for the Miami Hot Import Nights on Sat. Hopefully :-)

A SMALL PREVIEW:

THE REAL THING:-)
You can see the 220gph (not lph) fuel pump in the last picture.

That looks like the duct pipes coming from my furnace

Wrong. This Idea applies to cars that have clear vacuum/air pulses from the engine, but on a turbo car, that affect is lost and bigger is simply better.

Actually it is fine ( I did not expect to have that much clearance).

But we will see how it will be with the Tein Flexes

actually my friend you're the wrong one here. The size of the exhaust tubing does affect the spool up on a turbo car. Sure, going over stock size will make power, but going way past a bit bigger will loose power in the mid-range. Do you think that a 5inch pipe is better than say a 4 inch? Hell, I guess they should've put a 6 inch exhaust, that way more power will be made

. EVO racecars in Europe never use anything above 3".
