Posted 12/12/20 10:54 AM Share Posted 12/12/20 10:54 AM Guys Im running a BF F6 with 4" dump, 6" cat and dual 2.5 exhaust... The H brace that supports the Turbo is buggered and I want to do away with it because its a bitch to get on and off. So I'd like to know if anybody has come up with a better way to support the weight of the front half of the exhaust system? The manifold, turbo and dump adds up to a lot of weight hanging by the manifold studs... I can make a bracket that will hold the system at the back of the cat but thought I'd run it by you guys in case somebody has come up with a better idea? Thanks guys....

I've taken off the H-brace before without bothering to replace the manifold-to-head bolts with studs at all and just done the manifold-to-turbocharger studs/nuts and added nordloc without any issues with sagging etc. Link to comment Share on other sites More sharing options...

It's a pain but that's just part of life hey. I'd expect a workshop to do it properly so yerp Link to comment Share on other sites More sharing options...

I thought I'd get away with it but since the H brace has gone I've started cracking the dump pipe around the flange where it bolts to the turbo... I've migged it up with some bracing around the top flange but I reckon it'll break again with the amount of weight hanging off it...🤔 Link to comment Share on other sites More sharing options...

I've seen the welds on aftermarket ones crack, but never seen a stock one do it. Link to comment Share on other sites More sharing options...
