Fit's & Sounds Great
Bought this for my 2003 f150 XLT FX4. 2.5" in, 2.5" out. Sounds great. I bought this one for my truck 8 years ago and I bought it again in 2024. Can't be beat for the price.

This muffler worked great on my 1999 Chevy Tahoe to make it duel exhaust I did have to adapt from 2 1/4 to 2 1/2 but I have a mig welder so no problem there sounds very good with duel pipes out the back only aggressive when I stand on the throttle otherwise sounds good and tough 😁

The media could not be loaded. Wanted to add a more throaty note and the Flowmaster Flow40 did all that and more. Local shop zipped it in in just a few hours. Construction of the exhaust was great, especially at this price point. Hard to tell from the amazon description, but it's a true X-pipe design on the dual in dual out model. Now to see if there's a 4inch single pipe version for the Duramax.

AMAZING SOUND
The media could not be loaded. Installed this replacing the intermediate pipe and lately removed the end mufflers.Current config is:* Dual cat downpipes (its a V6)* Into Flowmaster 40* Out to dual 2.5" exhaust tipsFound this "squeezes" the sound making that more high pitched sound as you can hear in the video.It's a bit different from what I initially intended for my car (2017 - 3L V6 - Q7) but it worked out so good! It sounds total badass especially when upshifting and you hear that crack pops.... love it
