It tried the Thumpr. The Muthr Thumpr to be exact. It makes power. 502hp. And it idles like total ****. it's lumpy bumpy mess. sounds like a top fuel drag car. Turns every head on the block.

I have tried exactly 2 MuthaJunkers and despise them, I won't use them unless I'm absolutely forced (paid) to. J.Rob
