Wide Mouth Or Twin Dump Downpipe
 

Was just looking at getting a downpipe for my classic.
Lots of choice out there.
Anyone think the Twin dump style pipe's are better?
One that catch's my eye is the scoobymania 3in down pipe but thats £250.00.
£100.00 more than a middle of the road wide mouth
How do you think the different styles of pipe will affect the Lambda Probe's
Feed back?
:wonder:

open neck is the way forward
i replaced my magnex twin dump 2.5"
with a H+S 3" open neck , much better imho

Thanks for the reply Dazza

I've heard and read that the open mouth is better too.

Bellmouth with splitter by far better than any other design.
I posted a article from a Garret technicien before two years ago that explained why open neck with splitter downpipe is better.
Prodrive downpipe or Janspeed/H&S offer this design.

I bought mine for £150, it was delivered foc.

Polished downpipe, open neck design. 3" system narrowing to 2.5" so it fits the standard centre. IMO its fantastic value for money and fitted perfectly, it went on so well it only cost me £42 for the fitting - that was including the fitment of the tsl firestorm backbox at the same time.

purchased from the folk at www.subaru.org.uk
