I just installed a new killer b turbo with the down pipe and I now have a leak where the turbo connects to the downpipe. They didnt send me any clamps with the downpipe so I got one from my local diesel shop. I was wondering if I may have the wrong clamp or do I just need to fiddle with it untill it stops leaking. The clamp I have has two gaps on the grooved sleeves that stay there no matter how tight I clamp it, and that is where it leaks. Any suggestions :{
