FBD Exhaust keeps moving

Any one had any trouble keeping there FBD Exhaust still. I keep having to adjust it to keep it off the firewall. This will be the third time to have to do this. I take it all loose, shove someting inbetween the DP and the firewall and start tightening from the back to the front. I noticed this past weekend that it has moved again and is just close enought to bump the firewall when i hit bumps. Is there a better way to hold it firmly in place. I have the 4" turbo back. Thanks

I have never dealt with FBD so I'm not sure. I have the Silverline 4" turbo back and have never had a problem with anything coming loose. Are the clamps regular exhaust clamps or band clamps? I know I had to tighten mine a few times right after I put it on because the regular style clamps would be loose after heating up and cooling down, but no problems since and never had a problem with it moving.

I would just loosen everything up again, get it where you want it, tighten the clamps and then just tack weld each joint (1 tack weld on each side of connection). That way if it moves it won't be a big deal to grind them down. Also when you tighten your clamps, take a hammer and hit the clamp to try and seat it better on the exhaust and tighten it again. Hopefully this will help.

I like my Silverline exhaust real well. Very well built and everthing goes right in place and utilizes the factory hangers.

I've got MBRP and had the same problem, but only under WOT. I used some header tape and aluminum cable ties and pulled it towards the frame and away from the tranny lines & cab. Never had a problem since doing it. I'll get some pix tommorrow if you like. It's just raining like heck today...
