Spring loaded bolts.

 

if its leaking from the flex pipe, get a repair job done and replace the flex pipe. There is nothing wrong with your 4-1 piping from the manifold. just replace what needs to be done. do your research and find the flex pipe you need and go to a good welder.

This week I am meeting with two shops to see if I can get a dampening kit manufacturered here in north america to compliment header upgrades.

 

I went to a master welder he looked inside it and it had gone inside out. The same thing happened on the first one that they replaced before the manufacturer went out of business. There was no way to fix it. If you have seen one of these go you would understand that there is no way to bend it back after it gets as bad as it was. He ended up cutting the flex portion out and custom fitting a solid piece where it had been. This fixed my exhaust leak but it also causes added vibration to the vehicle.. the alternatives were to go back to stock or pay RRM another $400 for a product that may or may not hold up.
