Was wondering if anybody has used a trick one piece downpipe on a KB racing log manifold? The reason I'm asking is because my brother is upgrading his downpipe and I want to use his one piece downpipe if it fits. Thanks!

 

Does the KB kit come with two piece DP?

Do you have pics of the KB DP?

 

No the KB kit does not come with a one piece.

Here's a pic of the KB Downpipe:

I don't think it will be a bolt on. My manifolds put the turbo lower and farther forward. FYI, Tricks one piece DP's are not any better or make any more power then mine. In fact, I CHOOSE to build a 2 piece because it makes install and vehicle maintenance MUCH easier when you can take the down pipe loose and move it out of the way. It would be easier and cheaper for me to make a 1 piece DP, but by making it 2 piece, it makes it more user friendly on the vehicle.

 

So you have a Trick down pipe. But want to use kb's log.

Probably wont fit. Pipes from each mfg are laid out to fit their kits.
1 pc does flow better then cut and welded pipes.
But I did it for the looks, and fit primarily.
It can be slid in from the top or from the bottom.
Our 3.5" is a 2pc design.
Still fully mandrel just 2pcs.
That pipe being larger does help ease the installation.

 

I'm sorry Rick, but I have to disagree with this. My 2 piece pipes are mandrel bent and butt welded together, not slip fit or swedged/crimped in anyway, the V-band is also butted together, there is no difference in flow since the inside of the pipe is virtually smooth and no place for turbulence to form.

 

We can agree to disagree. No biggie.
