a bit of an update, been busy with a spare exhaust manifold and downpipe i bought off loon
i was inspired from this link
VWVortex.com - DIY: VR6 Exhaust Manifold and Downpipe Porting (Pic Intensive)
dont have pics from my exhaust mani before but you can see the difference in the link

downpipe cat end before

down pipe cat end after

back welded


manifold end before

back welded

manifold end after
bit rough but good enough for me

all after shots of my manifolds 6 hours of intensive die grinding!!!!

Forgive me for the n00bness, but what exactly did you do to the cat pipe? I'm assuming porting but yeah haha....nice job doing ti yourself though! I'd love to get into it

nothing just the cat end of the downpipe.

Yeah cool, but your cams with the GIAC tune is what you should be getting top end

i have heaps of acceleration from the 3.94 r and p and my 268 cam profile is good for mid range but top end is a bit flat
opening up the exhaust i think will give me more flow at higher revs, hopefully should work out ok
just hope i havent taken too much off.
