    Rated 5 out of 5 by from Very happy with my purchase Got this for my 02 gmc with the 8.1 and I was nervous about it being too loud, but it's is just right! Nice mellow tone but has a good bark when you get after it. Couldn't be happier with the customer assistance from jegs! Best price, free shipping, and an awesome product!

    Will this not fit a regular cab long bed?
