Exhaust leak

I have a pinhole leak in my 2000 PS 205 Silent Master (exhaust). Looking for advice: patch or repair, (JB Weld? Fiberglass/resin? or replace the part?) Thanks

Is it leaking water or exhaust?

It looks like you can repair it.

sounds like good news, removal looks like it should be straight forward enough, are there any tricks I should be aware of? can you recommend any specific products? I'm all ears...

I have patched a small leak where a bolt rubbed a pinhole in the exhaust with JB Weld, it has held up for over a year now. The hole was maybe 4-5mm in diameter.

A crack where the tube changes shape as it couples to either side of the exhaust hoses (as described in the Wake World post) will fail quickly with a JB weld fix. Patching with some fiberglass would be the best way to go in that situation.

Thanks, this leak on the bend from where the larger diameter cylinder bends down to the smaller diameter neck that is connected to the hose coming from the engine/manifold, sounds like I'm heading toward my first try at working with fiberglass, is all fiberglass created equal? or is there a particular type better suited for this application?

When I bought my 99 Maristar, the dealer had patched my exhaust with JB weld. Lasted only two seasons and was a PAIN to sand off. I put some fiberglass on it this past weekend. I went to Advance Auto and got the fiberglass mat and used Bondo resin/hardener.

One first timer to another, make sure anything you use that touches the resin/mat is disposable. Also, the fumes are terrible. I did it in my garage with the fans on and door open and still walked away with a rockin headache from the fumes.

Good luck! Should be a no brainer!

Auto parts house, generally will have a fiberglass kit. It's pretty simple. If you just have pin holes, JBweld will work. Sand and clean the area, first, befor applying.

Don't over tighten exhaust hose clamps.
