So you felt a little adventurous, maybe a little macho and decided to drill out your broken exhaust bolts but went a little or a lot off center and crooked?? That’s ok, I like to try new things too. No need to fear we can fix it right up for you!! (Most of the time 😂)

Come by and see us!

We’ll weld it right up, drill a fresh new hole and give it a nice clean surface.
