Does a MRT 2.0 with RES delete decrease HP?

Like the title says does a MRT 2.0 with RES delete decrease HP? All that I have done to the exhaust is the MRT 2.0's welded on. So would it increase rasp and decrease HP? Thanks in advance guys!

I got eight more horsepower with open headers with my no weeds on my LLT. You're going to get more horsepower with more flow of exhaust

If there are any rattles or movement in the exhaust causing vibration or sounds, it is possible the LLT's very sensitive knock sensors could pick it up and think it's engine knock. This would result in the computer pulling timing and a decrease in HP.

As long as everything is good and tight, you may see a small improvement in engine output with an axle back exhaust. Mostly they just sound meaner!

Are there exhaust any videos? And also what about the back pressure?

The stock exhaust, while large and heavy, actually flows very well and is difficult to improve on from a back pressure perspective. But you can make it sound better!

There are many vids on YouTube-

But wouldn't loss of back pressure affect horsepower?

Loss of back pressure reduce torque, not HP.
Should expect little lost of torque, but not HP, might gain a little amount of HP with straight pipes (MRT).

Hell yes do it! The MRT 2.0 sounds great!

You're not going to have any change in back pressure large enough to have any adverse effect. Got it?!
