While I was under the car performing a visual inspection on the ART pipes, I noticed the that mid muffler on my Shockwave had a nice cracked weld on the leading edge. No dent, but seems like I knocked something to make it pop.

To fix it, I went with the tried and true JB Weld epoxy putty. Comes in a cylinder with the reactive putty as the core. Knead it to solid color and apply. Ugly fix on a nice exhaust, but $6.99 was perfect for my budget on a Saturday morning. And it did fix the leak. Sound is no longer close to open down pipes at full throttle.

I'll keep an eye on it, but don't think I'll be taking the muffler off to get the weld fixed or ordering a replacement through Motordyne anytime soon. If anything, I may spend a project day to sand down the putty a bit. I Play Doh'd it up to ensure a nice and solid seal.
