Is this down pipe hurting performance? Engine is a 427", turbo is a bullseye comp r 83 with a 1.32 ar, basically a modified s480. The down pipe is 5" for about 6" out of the turbo, then necks down to 4" the rest of the way. Engine made 992 on 11#s and 1006 torque on a DTS engine dyno with 92 octane.

I just added a cutout about 18" from my turbo.
Sweet setup!

It is a tight fit with this turbo, had to cut up the core support a little to fit the intercooler and get creative with the headers and crossover. It all seemed to work out and is a blast to drive.[ATTACH]
