If you can whiff fumes are you sure you haven't got a bit of an exhaust leak somewhere?

If you can whiff fuel or gasses mr MOT man will also... that means a fail..

Is it acceptable to add an extension onto the tail pipe of the RC40? I've always thought ours should have extended further out the back. I wouldn't mind trying it to see if there is any further noise reduction. Daz.

I extended the tail pipe and front pipe of a twin box rc40 in the 80's to make a saloon exhaust fit an estate.

My new Rc40 has arrived. I'll fit it tomorrow and see where the tail pipe ends. I can always order a trim to extend it

The LWB version of the Maniflow RC40 comes with an extension that goes between manifold/downpipe and the front box, plus a tailpipe extension. I imagine the tailpipe is available separately. It's big though and has a rolled end - it's really not subtle.

 

Alternatively MIJ Exhaust will make an extension from any size s/s pipe with any size clamp-on expansion at one end for under £20 delivered. I've just had them make up an "exhaust joiner" from plain s/s pipe with one expansion (45mm ID) at one end but plain at the other end. Used it as a tailpipe. Arrived 2 days after the order was placed. Fitted onto the end of my exhaust perfectly. They'd make the exact length you want, if asked. I just chopped mine down from the standard size - gave me a chance to eye it up before deciding.

I needed something similar for the PUP. Seem to remember I bought a shiny end bit from halfords as I was passing. That's on a single box rc40
