does any 1 run an avo lowmount s/s manifolds from avo? suppose to be 30% more flow and 35%stronger with t3flange bolt on replacment?? i found them new for $880 just want to no if they r worth the money as il soon be bolting a 35/40 on low http://www.tuspeed.com/avo-stainless...old-p-743.html (http://www.tuspeed.com/avo-stainless-steel-exhaust-manifold-p-743.html)

Also very keen to hear about these.

I'm about to use one on my build picked it up cheap for $200, bloke thought it was the standard one. they are slightly bigger ports. few mm. benefits are its easier to weld external gates on it being steel and not cast. not quite sure how much power difference it would make. wouldn't make that much diff I reckon. plenty blokes have made really decent power on the standard vlt version. anyways I'm sure there's a thread on here with a picture comparison. Do a search.

I have one on the 31. It comes on boost a lot quicker than my mates 31 with standard vlt with high flow turbo and is smooth power delivery. We couldnt work out why until I found out my one was one of these as it looks just like a standard vlt from the outside except it has a blanking plug for a wideband.
