GN1 ext gate DP

[2toneNV]

What type of feedback can the people that have purchased a 3.5" or 3" ext gate downpipe with the bigger 46mm wastegate from Full Throttle or any other of the Buick vendors give on the quality, fitment and overall performance?

I have the 3", also using their headers which seemed to push everything closer to the fenderwell. Had to notch the fenderwell and the body seam for it to fit. If you have stock headers it may not be an issue.
IMO it seems to perform well. I have not put the car on a dyno or the track yet to verify numbers as I am still working on the combo.

Nathan,

Thanks for your input. For some reason ever since I joined this board it seems people respond more to the dumb, impertinent topics than to real questions that I THOUGHT this forum was intended for..... Turbo Buick questions.

These downpipes were designed for use with aftermarket headers like the Kenne Bell and ATR's that had the crossover come up into the motor compartmet. The downpipe sweeps farther out to clear that crossmember so doesn't matter if you use stock headers it will still come out as far.

Let me know how that DP works out for you.
I forgot to mention that the individual that sold me the exhaust system told me the 3.5" is for drag racing applications and is not necessary for street use. Someone looking for 9's.
