Who the hell makes a down pipe for an s400 or garret that will fit hsp uppipes? One that you don't have to beat the shit out of it with a sledge hammer to fit

Hsp's setup will work.. call dave and tell him what you're wanting to do he will take care of you :thumb:



I tried the hsp, it doesn't fit. Maybe the new style uppipes are flat like the stock and work?? But mine are round and it doesn't fit.

It works great with stock uppipes I know that. I just put there whole s400 kit on my daily driver and it clears no problem

Are your up pipes true 2" the whole way like the twin application up pipes? If so I don't know if anyone has an s400 downpipe that fits with those, pretty sure you've got to have the flat style passenger one for a 4" to work but I could be wrong

Have you actually called HSP to see what they have to say...

Knowing HSP quality and fitment, either you are trying to do something that isn't going to work or haven't tried the right combination. No way they would make something and market it that wouldn't work

I agree 100%. you should make the call to hsp and tell them the issue, they may be more help to you than us since it's their product you are having trouble with. :thumb:

Using a big vise and some wood will work wonders.



Yeah I tried alittle of that. Maybe I've just got a combo that doesn't work. They didn't knowingly sell me something that doesn't work. I think on my part I probably should have clearified but i figured it would work and bought it. Does someone make a pinched 2 inch ps uppipe?

Profab sells there manifold's and up pipes with a pinched PS up pipe for trucks running a down pipe in stock location .
Can you run a hood stack? If so bring it around the top of the motor and than up and out the hood.
