MJ Vr6 79 Posted July 2, 2007 Report Share Posted July 2, 2007 Yo peeps. Question time again...Just got off the phone with my guys at TopGear exhausts inn StAlbans, apparently the RaceLand 6Branch always cracks by the joints, Re weld is always an issue??!!!++**.Is this true, and is there any other 6 Branches to go for to put on my VR6?

Steve @ 1 Posted July 2, 2007 Report Share Posted July 2, 2007 Not heard of this being a problem. Mind you it is recomended that you uprate your engine mounts before fitting the manifold. Link to post Share on other sites
rodney 17 Posted July 2, 2007 Report Share Posted July 2, 2007 Same with all "Performance Manifolds". As they are made of stainless - they so don't flex like traditional mild steel ones! So you have two options. Fabricate a flex joint into your exhaust system or uprate engine mounts ! There are a couple of threads on this in the members sections to help you select the correct ones for your needsRaceland manifolds are not bad quality at all and there are many guys who have been running them with chargers/turbos for sustained periods are ok for them!Don't forget your heat wrap, steel tie-wraps and new bolts/gasket set.

matth76 1 Posted July 3, 2007 Report Share Posted July 3, 2007 You are right mate once you get a blow and try to re-weld it it never fixes the problem. A couple of major specialists don't recommend them for this reason. My 6 branch developed a small blow in less than 6 months and I have all uprated engine mounts and proper flexi joints the lot... just luck of the draw. As mentioned above stainless steel is more brittle as far as I know making it very prone to shearing when hot. If it was me and I was modding all over again I would leave the stock 6 branch on. Mine made no bhp increase and only a slight increase in torque but not noticable when you drive it at all. Up to you though mate. A lot of guys run them with no problems.
