A lot has changed since Rob ran those. ;)

So ill buy a new set of your manifolds and up pipes! What am I expected to gain HP/ET/MPH wise on a stock motor, single stock CP3, standard twin setup? If i dont notice a difference in the time slip, is there a return policy:D *But like said above, buy the best and do it once if your going to do it!

Yeah the repair makes sense I guess. Then just order them later once the motor is built and I upgrade to big twins later. Ill give it hell and worst that can happen is I have to buy I guess. Thanks guys. Being there's not a definite huge gain ill just see what happens. Thanks again guys.

On a side note- who is a good place to start with motor build options? Who builds them and has proven to hold or work well. Lookin for 850+ big twins or triples. Which ever gets me closest to 1000+hp. :D

You can buy them from me. Rick is not a vendor here . He recommends the XtremeFlow set for your application. If you are not completely satisfied we will refund you purchase price less shipping and a 10% restocking fee.

I put a set of cast flows on my dads truck. They made a huge difference! The GT4094 spools instantly and it made the truck a lot more fun to drive on the street.

Your uppipe riser bellow most likely blew from vibration. If the cap isn't supported they will crack eventually... Also I'm not much on uppipes and manifolds either. In a supercharged or N/A motor its nice to allow the exhaust to escape as fast and smoothly as possible. But since we have turbos our engines make power from exhaust pressure. Smoothing out the bends and and gasket matching doesn't change the pressure. It does however help exhaust exit faster, but again our trucks are driven off exhaust pressure. Just my take on it, not trying to step on anyones toes though just giving my honest 2 cents. If I had the spare money, sure I'd buy a set, but you won't see me saving pennys for them.

But please prove me wrong if I am missing something, I'm here to learn also.

That also makes sense madmax. I'm goin to take off the up pipe and c what it looks like and go from there. Being my truck will be down for injectors and twins might as well c what my options are there to. I'm goin to either fix it or say f-it and buy them and see what happens. Can't hurt. Like hearin everyones opinions tho.
