8v exhaust

[Mcwill]

Hi guys will the 8v exhaust be restrictive on my abf? It has no cat or centre silencer.

I would think a mk2 16v system would be better suited to the abf engine. mind you the abf is a couple of bhp and cc's up on the kr engine but that shouldn't bother it much as long as you get a decent brand of system. btw does your car have the lambda sensor wired in?

[Mcwill]

Hi bud yeah it does have the lambda sensor wired in.
Had a full stainless made up but think they just copied the 8v system that was on. Opps

Wont be that big of an issue. Youll lose a few top end bhp but will gain lower end torque. The new system is probably less restrictive than orig 8v system anyhow. Unless its a track car youll never notice the top end loss unless you drive around around on the redline all day!

Unlikely the main system will make a gnat's cock of difference.  What WILL make a difference is a tubular manifold from the likes of TSR.

For reference, DannyP's ABF Syncro made over 170bhp with a home-brew 4-branch on it and the rest was simply OEM Syncro (as mine is).

By my recent experience avoid Jetex like the plague!

Really in two minds about getting TSR manifold as its a lot of money, will it really make a difference? My current manifold is cracked so do need a replacement.
Is there any cheaper alternatives out there?
Also how hard is it to fit? Looks a tight squeeze

but gambit if it was low end torque he was after an agg would have done him .

maybe danny's car would have made 180 bhp with a bigger exhaust

macwill I get the feeling you want as much power as possible out of your abf. so I would defo have a decent 2 1/4 inch system at the very least. I don't see why vw would upgrade the exhaust from the mk2 8v to the 16v if there was no gain to be had. as for the manifold you may gain a few bhp and your engine should run a little smoother but the cost of them is ridiculous.

Yeah I think your rite bud I would love it to go like hot snot, I think it's just because people don't think it will be that fast, but I have to draw a line somewhere, so I'm going to do manifold and g60 gearbox with balanced and lightend fly wheel and remap and up rated mounts and that will do. Well for now
