Best 3.5" v-band downpipe with external gate

[49-blues]

Who makes the best fitting 3.5" v-band downpipe for use with a external race gate ?

you say "for use with a external race gate "
with a vband thats a given that you will need an external gate run off the headers

huffman( buickgn.com/gn1) is the only one that Im aware of offering such a pipe
his is a 3.5" pipe with vband for 3.5 pipe which most 4 bolt turbos are only a 3.o " pipe vband.
if your flange is about 4.2 outside measure it should bolt right up, if yours measures 3.58 its a 3" vband
be aware it swings way out into the fender and you're on your own for wastegate plumbing as to wether you tie it back to the downpipe or just exhaustt the gate down to atmosphere

i just installed one to a 7685 4bolt but it took a lot of fab as i had to replace the flange with a 3" , corrected the huge swing out into the fender liner issue , and corrected the dump pipe line up issues with the rest of the exhaust

if you want bolt up youll need a fabricator like brian cotton . send him your pass header ,turbo housing and have him build what you want

Good recommendation! I think I may try that, just not sure where is best to mount the race gate , I have a ATR 3" pipe that I wouldn't mind modifying -this will be for a 76 turbo 4 bolt t4 with a Q trim and later for a PTE 7175 turbo- hoping to do this right the first time.

we're going to be doing a batch of 3.5" downpipes in a couple months if you want to wait
