S16 exhaust options

[AustinAR]

git gti6 engine, instant 12 bhp gain, and about 12 lbft.

Not a massive option, had a spare engine for me previous pug but lost interest in that idea... Heard the s16 had better bolt on options so thought I'd get it for the long run...

Nothing wrong with the s16 inlet if it's all working correctly

Can do things like remove some material from the inner edges of the throttle body as there is a fair step down.

Match that to the diameter of the inlet manifold and the 8 inlet ports open out to the size of the gasket, all helps

As for a decat I had both a single type version and a twin pipe version, the twin was a Peugeot sport group a item and was far better than the sing he pipe version, either are hard to come by now though

Unfortunately the vacuum pipes snapped on the diaphragms, and it was an absolute b*****d trying to do things in the engine bay with such a large inlet, that was the main thought behind replacing to a gti manifold - I did love how it took off after 4k though..!!

I was going to port match & polish, the head & all manifolds are off - thought I'd dropped a valve...

What are other noticeable differences with driving does a gti vs s16 manifold have? Any mpg? If it's sucking half the volume of air does that make a difference?

You got any photos of the twin decat?

I'm tempted to by some mild steel and see if I can't rig a jig with my old manifold to make a custom branched one... Any comments haha

You really need to remap it if fitting a 6 inlet the difference is that large, But the basic tuning is better than a 6 with Cams being a easy fit etc

Oh really!! Wow nice! Where can you remap a standard ecu or would I be looking at the omex/mega/emerald route?
