Does anybody have the Dynomax Exhaust system for their truck? Summit has it for under $300 for the cat-back system. Looks like a good exhaust will be buying one.

I have the Ultraflo from dynomax. I like it. But I'm partial to Ultraflo since
I've used it on all my cars.

Does it have a deep tone or is it like stock?

Hey xterrock, is it a direct bolt on? What is the model number? does it replace the poorly designed factory y-pipe?

It has a medium to medium low tone and sounds nothing like stock.

I got the muffler off ebay for around $75. I just replaced the stock muffler
with the new one and kept the stock piping. I used 3" piping from the muffler
back b/c I thought the 2.5" pipe looked a little weak. Plus I wanted a side
exit instead of under the bumper. If you get the offset/offset 2.5", the piping
lines up perfectly. The cat-back kits I noticed seem to use 2.5" piping
anyways so I figured there wasn't a real need to switch out same sized piping
and pay a lot more money. The only benefit is obviously replacing the
scrunched stock Y-pipe. That was something I could live with. If you piece
together an exhaust, you can get the entire piping cat-back done at a shop
for around $100.

But even with changing out the muffler only, I did notice a difference. I
gained more top end.
