Watched this and went right and did it. Thank you sir. Way better! After spending $70k on a new trail boss and $8000 on 6" lift,wheel and tires. There are no beans left for any exhaust mods.
@@EssMotorsports Ty sir. I live in an apartment complex and have been debating straight piping for some time now, but I don’t want my neighbors to complain. Someone did this and put exhaust tape on the resonators and it sounded pretty decent.
Couldn’t believe it. Went to garage last night and sure enough there it was. 2017 Sierra 6.2. This truck has been choking its whole life. THANK YOU!!! 3 years of wondering why the truck hisses when pulling my camper……valve was seized 3/4 shut. Until last night. lol
@@EssMotorsports I’m hoping. I’m in the rust belt up in central Canada so it must’ve seized at some point. Broke it free and bolted it open. Truck immediately sounded like a truck, thanks to you. 👍👍
Use my reciprocating saw cut just before that valve and just behind the stock muffler and clamped me a Borla XR-1 in its place and its got a deep growl sounds great and the Borla won t rust there stainless steel paid $136 on Amazon for the Borla. I put in on my Trail Boss LT sounds great
Mine is AHEAD or upstream of the muffler. I wanted to retain that qiietstealth sound of the factory exhaust so I opted for the stainless steel motorized dump valve. It can be loud or quiet when it suits me. I put the dump valve ahead of the flapper valve and used a turndown to blow it to the side of the truck.
Great video, very informative. Love the before and after. You need to dual it.(won't be much louder justa little more rumble) I don't understand gms thought behind a single port. I bought the 20 Z71 LTZ
Put a Flowmaster super 44 in my truck tonight and ran into that valve so I left it and it barely changed the sound. If I cut it out and put a peice of pipe in there will that give it the normal effect? Or should I cut the valve and the secondary muffler by the tailpipe as well
Have you had any issues since this mod was done? How did it hold up? Just curious if anything had popped up since. Great video BTW very informative, well edited, and not too long.
So is this where the rattling comes from; I hear it randomly but while driving....I want to say low gear/ while going up ramps on freeway and we'll after I got it tuned to stay on V8 mode at all times...and actually I started noticing this after the tune and started getting the error code P-0430 too🤔
I have '19 Silverado High Country with a 6.2L. Mine as one valve before the muffler and one after the muffler. Did yours, or did it just one after the muffler?
Seemed louder and more rumble effect before. Idk, maybe it’s just phone mic and speakers being dumb. These type things are a in person thing so can’t really be sure through videos. I’d try it though and see 🤷🏻♂️
@@EssMotorsports yeah, I figured. That’s bad thing about videos, it don’t pick up all the sounds cause they usually have noise cancelling mics. It’s worth a try though
@@EssMotorsports I'm just upgrading to this from an old Dodge, so like, I miss the growl, but I'm also looking forward to the wildly improved fuel economy. 😄
I’m not brave enough to do a RU-vid video, if I do- I will probably try to do it like you did. Nicely done. That said… I didn’t catch if you mentioned what engine you have, but I’m guessing that’s not a 6.2. Maybe I should try it out and send it to you. I also don’t think I caught how long your screw was. I have a 21 RST 6.2 and the run up is disappointing to say the least.
Great video and hack. My 2016 6.2l valve is not working as it should, so I'm going to do this hack to try it out... honestly, mine sounds so bad at start-up as well as while driving I thought I had an exhaust leak at first. I may be swapping the mufer as well in the future for a little more rumble. Again, great hack. Glad I found this.
