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?
-
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 :undecided:

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

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

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 :grin:
-
they look very snazzy though :)

Got my new/second hand stainless manifold ordered :smiley:
-
I assume you ordered one for an abf? Otherwise youll have fitment issues against the tunnel but you can get round this by tilting the engine back a bit or bashing the tunnel
-
Yeah abf mate
-
Cool n the gang :)
-
The new manifold turned up today :laugh:

So the pipe diameter on it is 2.5" and as said before my exhaust is 2" so my question is can I cut the existing pipe off at the rear silencer and weld a 2.5" on? Or would the silencers need changing.
-
Get a decat section made up (bolts to 3 bolt flange) and then has a 2" end to mate with your existing centre section. Sorted :)
-
Thing is bud I already paid a good whack to get this system made up :angry: live and learn.
So was wanting to do it on the cheap.
I can buy a metre length of stainless, 90degree bend,3bolt flange and gasket all for under £50.
This is how it is at the mo.

So I was thinking where the top arrow is is where the new manifold should finish and where the bottom arrow is I could just grind off and fit new 2.5" bore.
Dose that look doable.
-
Buy something like this then just get a joiner between your existing centre pipe.

Been down to the see the guy that made my exhaust today and he can make me up a exhaust piece that will have a flexy on it and a reducer from 2.5" to 2"
Looking at about £50 dint think that was to bad.

Sounds spot on
