Fixing Kooks LTH that leaks

[The Game]

I've had my Kooks LTHs on since September 2015. I noticed my passenger side was slightly D shaped at the ball flange but went ahead and installed them and snugged them up. No exhaust leaks.

Jump to late May 2016. I installed my Whipple S2 kit and it leaks as of last week. We snugged up the bolts really good last week and it was fine for a few days but is leaking again. Is there any way to round out the edge with the header still on the car? I plan on getting copper gasket spray to try as well.

You are going to need a cone or tapered plug to round that on the car. Do you have access to a machine shop or somewhere that can make you a plug?

Channel locks and a ball peen hammer. I could tap that out in a few seconds.

Grab the flat with the channel locks, pull down firmly, but not enough to bend that area. Tap on high points on the side with hammer. This will release the tension of the bend and allow it to go back the way it was made.

I'm definitely going to give it a shot when I get back home from my 2 week work rotation! Thanks for the advice!

Tapping from the inside of the pipe or outside? Forgot to ask.

Yes, from inside. I've had a great results with spray on copper gasket but for stubborn exhaust leaks I used toothpaste like consistency paste and it worked perfect every time. I got one from autozone

No. Pull out/down on the flat and tap on the outside on either side of the flats. Look closely. When it was dented flat, on either side if the flat, the circle pushed outwards. When I get to work I'll try some ms paint pointers and post it.

OK, I'm no graphics artist :headbonk:

But pull down slightly on the flat, and tap very gently on the side arrows. Illustration is slightly exaggerated with the high points. You are basically relieving the stress on the bend when tapping. You're not trying to beat these spots down very forcefully.

Work it gently, then I would take a very large socket, like a 36mm, and lay it on the flat and tap on it too using the socket as a dolly. Yea, I'm a former bodyman. Used to massage bent metal for a living.
