Back box now changed but i have the old one and the valve was in the right side pipe.

Christ! I'm having a rough day I knew what I wanted to type and wrote the opposite

hi all, after the questions of how to fit the Powerflow exhaust last week I've now come to a dilemma or 2.

The bore/pipe diameter of the original exhaust is wider from the cat to the back box than the Powerflow one. The Powerflow was taken from a 2.2 (with mine being a 2.8). Circumference of the original is about 17cm, the Powerflow is roughly 13cm. Would there be a reduction in power if I changed over to the Powerflow one?

There is from what I've seen an electric valve at the end of the original exhaust. Can this be removed and would it be needed on the Powerflow one? What is its function and is that limited to the original exhaust?

Thanks
D

I would say Facelift as well because Ants is a facelift with the same valve

My 2.0 1999 facelift has the vacuum valve
