I went to MIJ in Walsall yesterday and had a Cat-back fitted.
Great service and the fitter wanted to fit just a new back box as he said my exhaust was in good condition.
I decided to have the system fitted from the Cat, as I will be keeping the car for several years and didn't want to have the middle section replaced at a later date.
He also told me that it would be a straight-through system, as apparently Diesel engines don't rely on back pressure, so no back box is needed!
Have to say I'm impressed. It still sounds quiet from inside the car, which is what I wanted.

Looks good.

Back pressure thing is a bit of a myth. An engine is just a pump. Quicker you can get air and fuel in an out the more power it’ll make.

Cheers Wozza. I'm fitting an ITG Air Filter at the weekend and then getting a Re-map, so hopefully it will give me a bit of a power gain.
