You have to remember as a manufacturer there are EU rules on noise emission, you can't just chuck on some aftermaket stuff, it all has to be homologated and have E number cert

And they tuned the engines of the day to suite there exhausts!

Just ordered two large 2.5" bends , cost £38 inc . Sparticus I used a grinder with a 2mm disc to slice open the cans and a grinding disc to grind the weld joint quite simple and quick to do , cutting the pipes out might be a pig , iam going to use a recipitating saw .

cutting stainless is a pig . you really need to do it in a machine shop with a cutting blade on a grinder or have it cut with a torch . i may draw up some plans for my attempt . i may go with square internal tube to make the jointing easier ! why make thing difficult ! ;P

^^^Thats how the GS boxes are done albeit with drilled pipe on the quiet side.

You could save yourselves alot of aggro and do it with flexi pipe and a 2 into 1 collector
