Well I had to get mufflers to correct my “fix it ticket.” I ended up getting a x pipe and dynomax bullets on my catback true duals for the new readers. Very disappointed in the sound. Going from straights to mufflers is depressing. No matter what mufflers it is and these are the loudest ones I could get. Not sure how I feel about the x pipe, I got it primarily to make the strange vaccum chop go away and it did that perfectly. However it might be contributing slightly to making it quieter, I don’t know. So if you’re out there and you want to make your exhaust a little louder- I can only recommend one thing (which i will be doing on my 18th birthday)- long tube headers, catless straight pipes with x pipe to 8” slash cut shorty tips.
2015 GMC Sierra 1500 SLE 31K miles. So I straight piped my exhaust and deleted the third cat now I get about 9 mpg literally went through half a tank in one day. Can anyone shoot me in the right direction as to why this is! My guess back pressure but I keep reading things that go back and forth about it. Long story short I just bought a new cat and borla atak full system to try and fix this issue. Running 93O
