I have the resonator removed and flapper hose clamped open and get no drone. FYI clamped open flapper is slightly quiter thann flapper delete...........I have done em both and have decided to,leave mine as is so,when I tow my boat I can remove the clamp if it's too,loud

Thanks for the info...this shouldn't be that hard of a decision. lol. maybe I'll have them remove the resonator first before going with an 18". I little drone won't bother me...its the chopper effect that I read about that I'm worried about.

 

My set up now with the res...I had my wife drive off as I stood in the driveway 10 feet away. I could not tell there was any difference. Although I told her to "stand on it"...she took off like she was holding a cup of hot coffee with no lid...

I had the 22" Magnaflow installed and resonator delete yesterday. The sound is a nice deep tone but is pretty quite and that was really my intentions. I suggest is you wanna here your truck at idle and I'm sure is noticeable on freeway ........get you the 18". The muffler shop was telling me 18" from the start but I'm happy with the 22". Nice and melow.

you have a video? I'd like to hear the 22" with no res

Sounds pretty good.

I installed a Borla GMPP Sport muffler soon after getting my '16 5.3L. It was still really quiet with the stock flapper and resonator. I had the resonator deleted today and clamped the flapper open. Sounds great with no drone and no chopper noise. Its still quiet while cruising but really growls when accelerating. My truck finally sounds like a v8 truck!

Did you leave the resonator and the flapper in?

I had a Dynomax Race Bullet on my 07,11, and 14 silverado. They were all the 12" body length. This time, I'm wanting something quieter on my 2016 5.3 silverado. I'd like to have similar tone as race bullet (deep) just on quieter scale. What suggestions do you have?

 

i messaged you about your 12" bullet! just looking for a review on it. Thanks!

Truck: 2015 5.3L with Borla S-type, resinator and flapper removed....

 

I have had the exhaust now for almost 2 weeks and CANNOT take the v4 Drone, whether local roads or highway and determined this quickly. Come to find out the Borla S-Type part number is for a 2-1/2" single in 2-1/2" single out.

 

 

Could the helicopter/drone noise be from the 2-1/2" Borla restricting flow ?

 

 

I need to make a change and dont care if i have to get the GM-Borla kit, i cant stand this fluttering sound, driving me crazy.

The helicopter sound is being exacerbated by the absence of the resonator and all aftermarket mufflers will exhibit this. Advise is to get a tune/tuner and delete V4 mode or try putting back the OE resonator. If that still doesn't get it right than the GM Borla will be your best bet.

Can't go wrong with the GM Borla exhaust. Too rich for my blood but the dozens of persons with it on this forum like it.

Any one have any idea if there is a Corsa dB series exhaust for the 6.2L? On their website as soon as you select 6.2L filter, all the dB series ones disappear. What happens if I put a 5.3L system on my 6.2L? My thoughts are that it's likely the same system (5.3 vs 6.2) except the pipe diameter is like .5inch less for 5.3L.

 

I'll have to give them a call.

So i hunted through several pages of search results on this thread before posting this but...here goes..

 

 

In my opinion, the best sounding aftermarket exhaust i've found is the Gibson Metal Mulisha exhaust, but i cannot stand the exhaust tip, im' not into that kind of look -- What i'm curious is which gibson muffler is the closest to the one thats found in that catback? I'm thinking it's the SFT Superflow Muffler (found here: http://gibsonperformance.com/c-1158801-exhaust-muffler-sft-superflow-muffler.html)-- As it's the only one with the same general shape as whats in the catback. With that being said, i'd be willing to try it out, but can anyone tell me the inlet/outlet of the stock muffler so i can be sure to get the correct model?

 

Thanks!

Here's a quick video of what I just got done yesterday. Magnaflow 11225 muffler, cut off valve and resonator. Sounds great outside but too much inside cabin noise when accelerating so I'm probably going to go back and get them to put the resonator back on. Sounds deeper in person:

Loudest muffler for 2016 sierra 5.3 with 3" stock exit exhaust? I've heard dynomax bullets, flowmaster 10 and slp loudmouth would be the loudest. Anyone have any reviews?

I havent compared, but my magnaflow 14" is pretty dang loud when i open up the throttle.

It's pretty calm for most daily driving and cruising speeds, but when you get on it it's beautiful.

 

My neighbors probably hate me. I am almost positive the guy at the end of the street does when i go WOT out of the stop sign.

      My First Project and GMC has me stumped

      By davester · Posted

      are there any codes? with lots of rust, perhaps disconnect/clean both sides of the connection/examine cable ends (the wires) for corrosion going into the sheath & replace if necessary/reconnect ALL the power AND ground cables between the battery, engine, frame, cab, fuse box and starter charm.li (website) has a no-start diagnostic procedure you can work through to get it working.

      OCI, not when but why?

      By Chuck FB · Posted

      Its no wonder you've gravitated to the oil types and brands you have in later years after trying certain brands and one being a specialty oil or at least very hard to come by up here and the other would have been a commonly found oil of the era and the vastly different outcomes as a result to using the vehicles in question the same distance for an OCI . It shows what marketing hype can do without actually having the product to back up the claims and that is no different now with the insane claims that are written on the side of a bottle of oil from some of the off the shelf oils.    What has surprised me and I was already finding this out before I bought my truck with the GDI engine, that this newer fancy technology that seemingly would suggest better fuel economy/emissions with this high pressure spray of fuel is not in reality kind at all to the engine or at least the oils life. Yet they insist on claiming long OCI with this technology just like they did with the port or similar type fuel injection systems when in reality its a step back in oil life to have a GDI system.    I think the mistake your making Grumpy is that your not sending your samples to Blackstone and getting the feel good glowing report that you can run it another 1000 or more miles and then send another sample where they say run it yet another 1000 miles and on and on it goes until your sending in something that looks a lot like road tar and then they may suggest you change your oil within the next 1000 miles 😆

      I am guessing that engines of that design back then had a better ability to be abused and survive longer than a new design engine with the long timing chain and the overhead cams and phasers etc. But I would never guess that an engine could go that far and not fail spectacularly or at least die a slow death.

      In the 80's 90's I'd run Honda's 7,500 miles between changes using Red Line HP 5W20 and do it for hundreds of thousands of miles with issues. Back in the day it was an SAE 20 with the HTHS of a SAE 30 and SN add load. It was also very polar. Oxidation VOA was over 120. Besides those motors were SPFI and lean burn tech. I could have likely run it longer but never did.    We had a Toyota bought new I ran on Pennzoil's latest and greatest synthetic of the day with "Penthane". A made up word for a very low dose of PAO. Tried 7,500 mile OCI's in that Group III/VI chemistry and the rings tapped out at 90K. Rocker box wasn't as bad as the one Punch put up but it wasn't good either. Also a SPFI motor.    I'm around 3,750 across the board on these GDI monsters and the oil it tapped out by then usually on TBN/TAN crossover and color. Red Line HP Euro.    The AMSOIL SS brochures tell you to follow the OEM values for the service class but that it can be run up to 25K if monitored. I can't imagine what motor could go that distance and not tap out. I've never owned one.    Yes, I know. Lot's of people do. I'm just not going to be one of them.

      I knew a guy in the early 80's that bought a new Monte Carlo and ran it a 100,000 miles without ever changing the filter or the oil. Just kept adding. It looked like that inside.
