Driving around normal the truck is quiet but the turbos are loud! My friend was riding beside me and said it sounded like a semi.... hah

WOT has a good sound with the stock muffler. Sorry I didn't really get that in the video. IMO it sounds like of like a 350/370Z.

Overall, I love it. I hate the way these trucks sound with an aftermarket muffler. I think that the downpipe+stock muffler is the best. My opinion.

Also remember that I have the resonator removed with the OEM Ford part from a 2010 f150.

I could live with that. I would keep the stock resi and maybe weld in some resi's where the cats once lived. Now I need to look for a OEM downpipe to mod. I'm guessing it would end up a little quieter. A new downpipe is just out of the budget for this year.

Not much. 3-5 rwhp about. Will get more turbo whistle out of a catless downpipe though. ( although catted will still give a good amount of it as well )

I just did a used MAK catless down pipe on mine (aluminized but I painted it to help it hold up to the elements longer).

Very happy with the results......judging by the "how far can I spin them" test I picked up some performance with this addition. The exhaust is deeper and ever so slightly louder running through the stock catback and resonator. Turbo whistle is greatly improved ESPECIALLY at cold start up.

Sounds like I'll be ordering a MAK catless downpipe! How long did it take to receive mrpositraction?

I bought it used from another member. Fitment was ok (but I did have to weld it back together where the previous owner cut it, and I did so before I put it on the truck), but they fit a pretty large pipe into tight space. The Y is HUGE compared to stock.

Very happy with the result. Went out for lunch today at work and had all the windows down, there is A LOT more turbo whistle now. I wouldn't say diesel like but maybe a baby diesel.
