up pipes leaking BAD!!
alright guys i have a L99 6 speed with an f5 5 inch straight pipe 6637 boost fuller guages and have my wastegate blocked and wired shut. My tuck has 250k and the uppies are leaking so bad i am building 18psi with my egts sky rocketing and fuel mileage is about 11-12. Now my question is that when i first got my chip i could build 22psi and then 20 and now bearly 18 on 120 or 140 is there anythig else that could be helping me loose boost.my up pipes are vovered in soot so is my firewall. Ik they are shot but is that why my turbo wooshs as it builds boost? I also built a leak detector and they are leaking so bad that when i hooked it up i lost 80 lbs like that not a budge on the guage. Help me understand why please?

I dont care what they look like(You can't see them in the truck) I just want something that is a good quality since they are a PITA to get to and change.
Do either of you have 1st hand experience with them?

When I see this I first thought wrong forum. The early 99s use the obs uppipes I thought. Then I looked at the riffraff site and confirmed my thinking.
Anyway. Late 99 IH bellowed up pipes are 420$ from riffraff.

Hope we all had helpful input.
