VW TDI Straight Pipe INSANE SOUND CLIPS - straight piped mk4 Jetta TDI 

I straight piped my Turbo Diesel Jetta for $70 and it sounds like a tractor. I'm not sure if it's the best idea, but it was cheap and I wanted to see if I could do it. I could definitely hear the turbo spooling up and it's a lot louder than it was before. If you have 70 dollars to your name, I recommend you try it too. Just use proper safety precautions and make sure you're not doing anything illegal.
Jetta Mods:
