Round tips have been installed in a rectangular hole, and i'm actually very happy with the outcome. I did have to make a exhaust hanger for the driver side exhaust, but besides that the install was fairly effortless. The tip size was 2.5" Inlet 4" Outlet 18" Long. I wish I ordered maybe a 2.75 inlet, because it was a STRUGGLE to get these to fit overtop of the stock exhaust. I figured the ID was 2.5" and the OD of the stock pipe was 2.5", so I figured it would slip on, I was wrong haha. It did change the sound quite a bit and im very happy with it. I also debadged it while I was waiting for the tips to arrive. Very happy to get that massive z71 badge off my fender. What do you guys think?

@f0urtw3nty I tore into it and got some measurements and pictures. initial pipe is 2" x 2.75" oval at the very tip, about 1.3" in it goes to a perfect circle of 2.5" but also the pipe is angled downwards, so if you put a tip on it it will be pointing down unless you made some kind of pie cut and welded it on. But, if you follow the pipe back to where it goes flat, it looks somewhat level with the bumper cutouts. Only thing is that the hangers are in the way. The passenger side looks like you can cut it just before the hanger and possibly keep the passenger hanger, but the driver side is going to have to get removed and rewelded on. It's in a completely different location so that makes no sense. I ended up ordering two exhaust tips at 2.5" inlet x 4" outlet x 18" in total length. That should be more then enough to span the gap with a little bit of tip poke like I wanted. They would get here around the first week of August. I can only post one picture cause of the size, but you can see the S bend in it and the hanger location. That picture is of the passenger side

The factory tips dont touch any part of the exhaust and are as you said aesthetic. In my case I'm choosing to change the tips because I dont like the looks of the factory tips as well as reducing the drone by getting the exhaust futher away from the cab (instead of just dumping below the box like the factory tips do). Not only that but a "real" tip would change the tone of the exhaust. @f0urtw3nty Unfortunately I got rained out Friday/Saturday and got called into work Sunday so I didn't make any progress. So we're going to have to wait for another weekend but atleast I'm motivated to do it now.

I've found pretty much nothing at all, looks like no one is making tips for the new gen trucks, only full exhaust systems with integrated tips. I did send a email to MBRP to see if they had any tips for the new gen Silverados and they said no, and were not developing any as of now. I'll definitely measure and see how far you would need to cut back to get rid of the oval and make it round. Should be really easy to tell with a caliper. The only thing I would be worried about if the piping is angled down or up by a little bit the tips would also be angled. I'll tear into it this weekend and remove the fake disgusting chrome tips and get some actual measurements / mockup pictures. Like I said before I do have a 2.75 inlet to a 4" (or maybe 5") single. Even if it wouldn't fit I'll take some pictures just to see how a round tip looks in a rectangular hole.

Not yet no, I haven't really had the time. Plus I've been searching for more tips that are actually made for the Silverados. I'd rather install something that fits and doesnt leak then put a tip in a vise to ovalize it and hopefully make it fit. Maybe I'll try some more this weekend once I get home from this long haul.

Can you tell a huge difference between taped vs non taped?

Personally I really feel as I dont have any drone, I dont know if I dont hear it because of the 33's or what. My old Silverado had tonnes of drone so maybe I'm used to it? I also rarely hear the DFM kick in, and if I do it's only at low speeds, never on the highway.

Theres some clips for you, hopefully it all came out ok. Sounds great, I'm considering taping up my mesh screens now too, are you enjoying it? Also you might as well kiss your gas mileage goodbye, I always romp it because I love the sound haha.

I just went out to measure it, pipe is 2.75 all the way to the fake tips. One thing your definitely right on is that the tips are ovaled, so that sucks. I'll take a better look to see how far you would need to cut them back to get them to be round.

Absolutely, I just left for a long haul this morning, so once I get back in a couple days I'll edit and upload what I have. I think I have external from a dig, external fly by, and external cold start. Let me know if you want any other angles.

I have cut the flapper and muffler off of my 19 Silverado with DFM. I left the screen resonators and it sounds great. I do have the 8 speed transmission and the z71, so I have 6 screen resonators instead of 3, and I also run fairly aggressive 33's. I dont really notice the DFM at all, if anything I only notice it at lower speeds. You do hear it kick in but it's not that noticeable. I did the same thing to my buddys 2018 gmc 5.3 and you can REALLY hear the v4 mode. And I left the flapper in on that but forced it to stay opened. The "cold" starts are pretty loud, and it gets louder the warmer it is outside and that makes no sense to me at all. If you have any questions just quote me and I'll respond. I could get some sound clips too if you liked.

The stock exhaust pipe is 2.75", I have a 3.5" tip that fit on my old cat eye Silverado, I might give it a test fit when I get the chance

Hello, I've been looking around for some exhaust tips because frankly I hate the rectangular fake exhaust tips on the z71. I've been seeing pictures of dual oval tips and I do like them, but I'd rather have bug singles, like a 3" or 3.5" . I've really been trying to find some pictures to see if it would fill the rectangular bumper cut outs, wondering if anyone here has done it.

I think it depends with what model of exhaust you have, my truck is a z71 model and I cut off the flapper and muffler and just put a straight pipe in. But because the z71 is a dual outlet it has 6 mesh resonators instead of just 3 like the passenger side exit exhausts. My truck has very very very little drone if none at all. Maybe since I run 33's it might be a lower RPM but I doubt it makes a difference. I did originally do a stright pipe but the initial start up was pretty loud. So I went to a borla pro XS instead. Really nice muffler. Quiet when you want it to be, loud when you want it to be, but I went back to the stright pipe because it was too quiet for my taste. But then again it could be louder on a single passenger side dump.
