You ever go to a place like Midas/Meinike and are give some insane price for a muffler and some piping. For this instance we will say $475. So, you decide to shop around and stop by some shop that looks like it has seen better days in a what you think is rougher area. Well, this exact thing happened to me and was told I didn't need a muffler and it would be $90 for the piping.
Besides a a low price this father and son team really gave great customer service and got me on the road pretty quick.
If you are military they give discounts too. This is just another reason to keep it local.
