Armo325 Posted March 30, 2019 Share Posted March 30, 2019 I'm kind of swimming upstream here but I'm trying to get my hands on the exhaust "flapper" valve that everyone is cutting out and throwing away. I'm looking for one from the Silverado 1500 exhaust with a 5.3L motor. I'm hoping one of the members here still has their stock exhaust lying around and wouldn't mind cutting the valve section out and throwing it in a box for me. I'm in Virginia Beach. I'll obviously pay for shipping and am happy to send a little something for the effort. Thanks in advance. Quote Link to comment Share on other sites More sharing options...

Armo325 Posted April 2, 2019 Author Share Posted April 2, 2019 Just wanted to give this one bump before I started looking elsewhere. Not too many options in this area. Thanks in advance. Quote Link to comment Share on other sites More sharing options...

Bohanan23 Posted April 2, 2019 Share Posted April 2, 2019 In a few weeks I plan to remove my full 5.3 exhaust.. If you're still looking I can have it cut out and shipped.. But it wont be for probably 3 weeks or so. Still waiting for my long tubes to come in 1 Quote Link to comment Share on other sites More sharing options...

chadvl Posted October 25, 2019 Share Posted October 25, 2019 I am new here have a 2014 1500 Silverado and have issues with the truck switching from v4 to v8 long story short can I leave the exhaust flapper valve open w/o voiding any warranty I purchased an extended warranty so don't want to void any any info would be great Thanks Quote Link to comment Share on other sites More sharing options...
Yondu Posted October 26, 2019 Share Posted October 26, 2019 Op, keep in mind there have been a few revisions on these. 3 I think. Mine is before my muffler on my 2018 5.3, they are after on the earlier trucks. Quote Link to comment Share on other sites More sharing options...

Just get a band clamp of some sort and clamp it in the open position. When the truck is revved, it moves to the open position, so crawl under and have someone rev it. Then twist it fully in that direction and clamp it open. This will do nothing with switching between V8 and V4 by the way. All it's going to do is give you a little more exhaust note and give you a fluttering/helicopter noise when in V4. Totally reversible and will not do anything to the warranty.
