Re: [DML] free flow exhausts-legality?

[Martin Gutkowski <webmaster@xxxx>]

With reference to the system we in the DOC UK are having made:

1) The main problem with the stock system is that the piping is rigged to get the exhaust
through the cat. Remove the cat, and why bother with all the rest of the crazy pipework.
Our system will replace the manifolds and feed them directly (no cat) into the back box,
which will look exactly like the stock one except for having a inlet on both sides. I
personally do not intend removing the lambda system.

2) The "noisiness" is up to you - these are made to order and you can specify as quiet or
loud as you like.

3) The lack of cat is bothering you guys a bit. Remember the first generation Island Twin
Turbo and the BAE turbo systems got rid of the cat.

4) The cost is around $1200 + shipping.
