Muffler delete will definitely increase noise levels but the resonated X pipe makes it perfect.
What you could do is replace your stock resonators with aftermarket like vibrant and add an X pipe. This should help a ton. The stock resonators suck

Looking at your pics to find a muffler/resonator that's got 3" in/out...you've got a factory x-pipe installed just behind your resonator that's partially covered by the exhaust brace  |
I've asked this question on his other post and trying to clarify, even messaged him... no response. As you stated his picture shows the oem xpipe still in place behind the brace and the oem resonators replaced with the 2.5" Resonated xpipe. It appears he has 2 xpipes nearly back to back. I'm confused... plus I would think the 3>2.5>3 in flow in itself would pinch performance.
I have catless downpipes and a muffler delete running 700whp. I'm going crazy trying to find the perfect solution to remove the drone and NOT hurt horsepower numbers. This looked like a viable option until I noticed the 2 xpipe pic. Maybe he straight pipes the oem xpipe after the Magnaflow Resonated xpipe was put in place of the oem resonators.
If you can find a 3" Resonated Xpipe please let me know.
