Tank_VR 25 Posted May 23, 2016 Report Share Posted May 23, 2016 I don't know if i've posted in the right place, although I'm being lazy and wondering if I can get away without heat wrapping my 6 branch. I know what its like heat wrapped, has anyone got any insight on what its like without being heat wrapped, Also if it makes a difference, pros/cons Thanks in advance Bealieboy 1 Link to post Share on other sites
VR6Pete 1,455 Posted May 23, 2016 Report Share Posted May 23, 2016 I've heard stories with them cracking. If it's off the car currently then recommend that you wrap it or have it ceramic coated. Apply the wrap whilst it's wet! Tank_VR 1 Link to post Share on other sites

I don't want itchy arms, but I guess it has to be done I heard they crack/leak from where the manifold meets the decat.. so I was thinking to get a flexi pipe welded Link to post Share on other sites

Wear gloves and apply wet. Helps a lot. You will also need some metal ties (lots of them). I've had a stainless manifold for years on all my VR's and never had one crack. They would usually only crack if you have bad engine mounts with excessive engine movement putting stress on the manifold. Tank_VR 1 Link to post Share on other sites

A wrap is therefore recommended and advised to drop bay temps and also it's suggested that keeping the heat inside the 6b via a wrap will also aid exhaust flow- draw the gases out quicker. If you're buying a wrap, go for a titanium type made by dei, these are much better than a fibreglass wrap because they stay looking nice for longer and smoke much less whilst they mould to your 6b. It's also recommended to use a special silicon spray to waterproof the wrap and therefore preventing some corrosion. My fibreglass wrap has smoked for 300 miles and approx 7 hrs, titanium smokes for about 15 mins! VR6Pete, Tank_VR and VR6CABBS 3 Link to post Share on other sites

Yeah fair enough! recently changed all three mounts so that shouldn't be an issue Link to post Share on other sites
Bealieboy 1,625 Posted May 23, 2016 Report Share Posted May 23, 2016 Only fibreglass ones are suggested to apply wet, titanium go on dry. VR6CABBS 1 Link to post Share on other sites
