Today's word is fab-ri-ca-tion.
From the intake to the downpipe to the rest of the exhaust and all the way to the tips, we've been busy fabbing up a bunch of aluminum and stainless steel tubing.
The GT3076 is a pretty big turbo - big enough to present clearance issues when used on the quattro version of the TT. Bascially, there's very little room between the exhaust side of the turbo and and the quattro's rear propshaft. Adding to the degree of difficulty is the fact that the turbo exhaust outlet is situated perpendicular to where the downpipe needs to go. We tried a few configurations and finally came up with a downpipe design that clears nicely and with no restriction penalties.
After the downpipe is straight 3" stainless steel piping that ends in a Magnaflow muffler with dual outlets. We're still not sure what style tips we'll be using.
On the intake side we used aluminum tubing with the goal of minimizing the length between the turbo, intercooler and throttle body, while still allowing for a functional upper stress bar. Speaking of intercoolers, we're still waiting on ours and won't be able to complete this job without it. It should arrive soon, though, so in the mean time we're trying to button up everything else.
