My dad has 2 sets of bypass pipes from warren Engineering. Great mod and pretty sure they don’t make them anymore unless you make a big order. Might be wrong.

£55 posted a set.
 
Maybe interested but can you post a few more details and photos thanks
 
Hi sorry for the late replies. I’ve been away on work and just completely forgot about this post.

For people who want to know what they do, I’m not 100% of the procedure but 2 holes are drilled at the back and and front of the back boxes. These are welded on, it’s to do with the gases and improves noise and improves rasp.

I’m sure someone else can confirm how it works

I did ask warren engineering if they can make some and they said yes if you want to go down that route and none left. They were 28 plus vat for 4 sets

See my post in the m specific area
 
They are still here. They’re are 2 sets left. I’ve just had my fitted by eta motorsport. Sound amazing but sadly can’t put my foot down just yet as bedding in my new shells
