6.2 MRT J Tube Exhaust

Rated on a scale of 1-10... I have had 4 different exhausts so far.
1st was complete Stainless Works from engine to tailpipe the sound was fantastic but the drone was horrible. 9
2nd was Borla sound was great drone was a 7
3rd was a JBA side exit sound was great drone was 7
4th I currently have is a MRT rear exit from MRT Engineered Performance sound is great drone is 1
I have to say so far over 4k miles driven this is the best for me for sound quality and drone. They use the J Tube to change the drone frequency so it is not noticeable. If you want a great sound with zero drone

I've got a Black Widow exhaust and added a J tube before snoball. Went from wild drone to almost non existent. To the point I could hear the wind whistling by my hood lights.

The J tube works.

t_j's custom exhausts to the rescue. I have a Stainless works muffler 3in 3out offset to centre with the same J-Tube as @NE Ford (he has the other half of the stainless mandrill u-bend) and there is almost no drone (turned down before the axle).

What did you use for length, and did you buy or make the end cap?
Im about to make one for the annoying Roush exhaust on my 14

I used 26" OAL

All 304 tig welded with 309L as the stock pipe is 409 not 304.

Straight section was 18" plus bend put it in the 22-24" range depending on how you measured it.

If the end of that isn't supported it's going to break at the weld.

It's supported on the other end of the tube and muffler by a link from the muffler exit to the j tube.

Ok. Phew. Ha. I actually had to double take and zoom in. You can barely see that.

Yeah its kinda blended in with the background junk there, but its pretty stout, there isnt much weight in the J-Tube so it should not tare out (famous last words!).
