LB7: Intercooler piping and Y bridge

[MAXX IT OUT]

I am looking at doing 3 in piping and modifying the Y bridge to all 3 in. I am looking at MBRP piping, but I have read that they well not work on the stock Y bridge on my truck(because it is a 2001). Any one have anything that is used that they want to sell or any suggestion on what to get.

Jason Wherli who is quadracer on here could make you a 3 inch y bridge and a 3 inch hot tube and you just trade yours in.

he's looking for stock y bridges now too WcFab.com great guy, awesome products.

 

[MAXX IT OUT]

Are his y bridges with stock style piping or his own piping?

He can do anything you want your cold side pipe is different so he would ha e to make that different anyways.

What is the problem with the 01? Is the y bridge smaller?

The intercooler pipe boot and y bridge are 01 lb7 only

Not to say that it wouldn't work on any lb7 of any year

So my stock bridge is the restriction?

It is on any lb7 I was just stating the 01 bridge is different and the boot is different if you had a custom bridge made you could possibly need a different boot 02 03 04 take a straight boot.You will want to get rid of the intercooler 45 boot and the sweeping 90 boot off the charger to the hot side pipe if you haven't yet boots that make bends don't play well with bigger boost it will sound like a grenade when it blows out......mine did

Ah okay, that helps, thanks. Ya I noticed the hot side boot and mine is definitely soft. So I probably need to correct that soon.

Mbrp is cheaper then say afe or just have a custom 1 made the mbrp straight boot blew out on me also and I got a 4 layer boot from boostcontroler.com no more probems now.

the coldside pipe should be the same just need a 3"x2.5" 45* boot to make it work
the stock LB7 hotside pipe just sucks plain & simple

Anyone ever cut the reduction off the cold side pipe on an lb7 and ran a longer 45 boot?

 

[Noreaster]

seen the reduction cut off & a bead rolled on it to connect to a 3" bridge
