Hi, have a magnex full twin system on saph4x4 which sits up nice and tight including the back box which doesn't hang low like you see on some saphs. However where it splits into two pipes at downpipe from manifold, one join is a sleeve fitting and the other is a bracket with bolt either side. No matter which way you turn the bracket it still sticks down about 1.5 inches, enough to scrape on the speedbumps if you centralise them to go over at normal speed.
Has anyone out there got round this by adapting second pipe to a sleeve fitting also, or any other ideas. Several exhaust experts out there have said nothing can be done and you just have to live with it. Appreciate all comments. Cheers.

 

Nature of the beast mate,you going just have to suck the lemon.You want to come where i am.20mph zone all yellow sleeping policemen and speed humps,i cant even take the kids to school or go to asda without hitting them.The only thing i have found i can do is straggle two humps at one time.Anything else just results in a big fat scraping noise and everyone looks at you.My pipe is 3 and a half but the car is standard ride height,its been off 3 times now !!

 

I have exactly the same problem, tried loads of things but it still scrapes
