In a perfect world i would have completely remade the mid pipe, but the Kooks exhaust Nick supplied wanted to be used. Unfortunate that the way its made (which is well) had the 3 bolt flange style connections at the back tails. I wanted to keep the exact same geometry as the exhaust was made, in order to not have the issues out the back and alignment. I looked at the x on the bench and figured with some manipulation i could convert it to a pseudo Y by removing one leg, porting out the crossover and capping one end. The down pipe that wasnt finished was 3.5 od and no real way to make a clean leakproof connection. I flared the spare leg i removed to take up some space for the reducing weld. Coming off the downpipe its right into the leg and then gets split equally at the x with the internal work i did.
The spare leg also had to be sliced and the flange spun in order to meet up to the exhisting 3 bolt on the midpipe. All in all i was quite happy to keep the exhisting exhaust intact, which resulted in a seamless install of the rest out the back. Everything lined up perfect.
Now onto the few things that have to be tweaked.
Im surprised with whomever fabbed the hotside. Everyone knows a wastegate should be mounted at a 45 to the pipe leading the the turbo. We have MAJOR boost creep even with the 44mm gate just running on the spring (13psi/.9 BAR) By the end of the runs its was closing in on 18psi, which deems the controller useless for now until we fix that. I have to drop hot side now and refab. Exhaust has a real hard time making a 90* turn to exit the gate....never gonna control the turbo like that.
At 15ish psi and a lame tune @ 5300 rpm we are alredy well beyond block splitting terr, so new springs and fixing the gate is next in order.
Thanks for the props.
