you will be making your own or having somebody make one. The ATP swingvalve is great and then the 90degree 3in vband and the rest after that becomes a fab job. a performance shop with somebody that knows how to cut and tig could make short work of it on a lift as mine was done on my daytona r/t here in NJ

Are you still using a TIII turbo turbine housing?

If so, I have a flange you'd want to buy, use with 3 inch pipe, of course.

Bill,

I used the ATP V band outlet and the 90* with one long leg on it. I cut 90 right after the bend and used 2 bends out of a stock style 3" down pipe along with a flex section. I'll send you some pics.

If its similiar to the FM Unit, then it flows, I am bringing it up again but Larry used one and got 500whp with one, :thumb:

This is the ATP one. It' hard to find unless you search for swingvalve. Looks like it's a cast model now, the one I have is all welded stainless. I haven't seen the FM one.

I didn't see that before but that looks like it will work. You might have to put an angle cut on the lower end to line it up. For bends like that Racing Solutions in the vendor area is more reasonable.
