I managed to get a very cheap pair of valved mufflers off a 4.7 GT, these I'm trying to have fitted on to my QP. The tailpipes are a few inches shorter than the QP. I'm guessing this is weld work?

I was toying with doing this and glad only a minor extension is required, but have decided to do cats first. I do have a baffle rattling in my right hand box though. Are you planning on moving yours on or keeping for swapping back?Just an upate on my exhaust modification project:
I got the QP back today and the sound is absolutely incredible and unbelievably loud compared to the stock QP, visually you couldn't tell the back boxes are from a 4.7 GT.
- I had standard back boxes in my 4.7s QP
- I bought a valved pair of quad tip stainless back boxes from a GT 4.7 (for very little money) and the valves move freely
- I had the tail pipes extended by an exhaust fabricator which cost £300 (more than the cost of the valved back boxes alone)
The valves are permanently open for now and this weekend ill connect up the vacuum lines and switch for the vacuum solenoid valve. I decided to build my own kit rather than buy one.
Pictures to follow.
Best

No problem. I may look out for some cheap gt if they are worth doing. May as well go full asbo.Hi, decided to keep for now just in case i need to go back to stock.
