Will full race downpipe work with peakboost manifold??

[Driftzenki]

Hi guys, just wondering if anyone has done the combination of a peakboost manifold with a full race downpipe, issues with runner clearance or any other issues?..will they work fine or are there any modifications that need to be done?

It all depends on how far back the PB manifold places the turbo versus the FR manifold. From what I have seen, my PB setup places the turbo farther back then a FR.

from what i remember

the peakboost kit the manifold to turbine housing flange is angled
and the full-race manifold is more parallel to the motor

in reference to the non-twin scroll manifolds

and the full-race twin scroll manifold put the turbo closer to the front of the car, so the downpipe is "longer"

i dont think it will work.

i was searching for this exact question 2-3 years ago when i was trying to piece together a turbo kit. i ended up just doing all full-race parts and they all bolted up together perfect.

im going through a mission trying to get a downpipe for my set up, its a peakboost mani with a precision 5857..local muffler shops charge an arm and leg for a custom pipe and all i really need is the peakboost turbo outlet cause i already have a full apex exhaust system which includes the downpipe..came across a full race turbo outlet thats why the question..did some measurements and i dont think it will fit either..might hit the firewall or brake booster.

Just buy the needed PeakBoost downpipe... It bolts up to the turbo and eliminates the testpipe/cat...

Yup the Peakboost downpipe is great...I think PB is out of business now so used maybe your only option. It has a built in flex pipe and mates with the Catback without the need for a test pipe. Its also two pieces with Vband in the middle (Joint right where the firewall ends near tranny) so you may be able to get the upper half and then have the lower made.
