External DP with Deltagate?

[T Spool]

Does anybody make a 3" stainless down pipe with external Deltagate flanges? (Besides the old ATR's)

In my opinion if you want an external wastegate, you should consider installing it in the cross-over pipe to reduce some of the exhaust flow in the restrictive passenger side header. Then the down pipe can be ANY of the ones out there. Just install a block-off plate for the WG hole.

Here's how I did mine. I have a cross-over with a Delta-Gate flange welded on it of you need one. I went with the 48MM Pro-Gate for "up ward mobility". The Delta gate I have needed a valve seat re-machine, so I removed it and used another cross over for the new 'Gate. IF you leave the gate open to atmosphere it gets kinda loud at WOT. That's why I ran the stainless tubing to the "test" pipe.

My deltagate is also mounted on the cross over pipe. I have the pipe just going to the atmosphere because i had to hack it off since it was in the way of taking the trans out.

Havent had any complaints yet about it. Is pretty loud when letting off.

Thanks guys!:smile: I try to make things as nice as I can. Budget gets in the way alot of the time, but I do what I can. As soon as my shoulder heals up (surgery for the 7th time) I can install the roll cage, nitrous system, rear suspension upgrades, and then hit the track for some good low 10 second runs with a "bunch of crap I had laying around my shop". :biggrin: (Geno came up with that one! ) Here's pics of the rest of the engine:
