I'm no numpty when it comes to engineering, but is there a sequence to fitting a JL exhaust. I assumed that the stub manifold is tightened up first due to access to the two brass nuts , then the main exhaust slots in the stub and onto the shark fin bracket (it's an Avanti top end by the way), but I can't see how you can get the bolts in the shark fin bracket etc. Am I missing something obvious :oops: :shock: :?

'twas sent to me by Martin (Corrado) who I bought the Avanti off, so should be the right one.

Have you bought the Avanti Franspeed ? if (as it sounds) you havent you will have this issue of bolts to close to fins and been unable to fit it correctly, you will have to make an alteration to the bracket (there is a picture on here of the alteration I will find it and post) you can grind out the fins to ease the bracket, BUT I WOULDNT, If you didnt remind Martin you needed the zorst to fit Avanti i doubt he would have remembered tbh, he gets dozens of requests everyday. I did btw buy the Avanti franspeed which Dan sourced for me from Andy Francis and fit the Avanti kit perfect.

Funnily enough, I've just been modifying an Avanti in such a manner so that I can fit my older JLs if I decide to in the future. However, as already stated, the revised Franspeed JLs fit with no modification required.

Martin confirmed it was a Franspeed Avanti Tour exhaust which I have now managed to fit without resorting to grinding down any fins. Had to grind down an 8mm nut to 5mm wide to fit between bracket and cylinder and what a fiddle that was trying to fit it on the bolt in such a narrow space, but all there now. :D Also had to dremel off a bit of the scalloped out bracket so I could get the second nut on to secure to chaincase, but all fitted and solid.
