It shipped in 2 days on free shipping! Absolutely love the finish on the angle cut! Possibly doing a dual setup in the near future!
aussie stacks

i just got through installing the 6in aussies on my 7.3 powerstroke. i love the sound they make, and how some people find the truck a little more intimidating.
Great kit

the tips that we got from this website are great! we put em n a 04 dodge 3500 and the black smoke boils from the pipes and also gives a great tone to that 5.9L diesel hum
