Is there such a thing out there?

I really don't want to do a header swap.
 
RJC d/p will workfrom what I gathered from a communication w/Jason. I run ATR's also. I need a v-band for my new turbo, and Jason isn't ready to make an adapter yet. His d/p does come w/a test pipe as well and it's 4". Mark, TR Customs, offers 3.5" gn-1's w/int. or ext. gate w/gate in cluded in the price.
 
I called RJC and they said it wouldn't work with ATR headers. I had a GN1 pipe, that didn't work out.
 
I'm going to try a different GN1 pipe, and I'm going to Sam Swope RIGHT NOW to check out the 2011 Buicks, thanks to the above advertisement. I never knew they existed until I saw that ad. MY LIFE IS NOW COMPLETE!!!!!

Sack, whatever you do, do not get rid of those ATR Headers!! You will never find anything close. I have installed many....
 
I got another pipe from GN1, the 3.5 without the wastegate setup. It fit really nice, they re-worked it where it goes under the car. Archie even called me to make sure it was right.

I haven't mounted it yet. It's going on the header and back into the dp.
 
Ok, I called Jack Cotton on the v-band and he said I would have to bring the car up to his shop to have it custom fitted for the 4" D/P as I have the a/c still in the car.
But that's a 1K drive and the engine's out for rebuild, so that's not going to happen.:frown: Post pics when you get'r-done!:cool:
