Sport / 3.0 in Cat-Back SSE 4.0 in Twin Tips | 11-13 Silverado Sierra, Denali 6.2L 143WB (14523)

Disappointed

This is my second exhaust system, first was a 2000 Silverado with a 5.3 liter , exhaust was fantastic, second system was a 14523 on a 2013 6.2 liter, after starting the vehicle we all noticed how quite it was compared to my 5.3 liter, I called tech support and I advise they sent me a touring system not a sport system. Matt advised that not all mufflers are the same I’m very upset with this system, I’ve had the system for 5 months , it’s a good thing I saved the factory system

Corsa Exhaust 14523

Received my exhaust system, opened the box to find everything was there except the intermediate pipe clamp , I called for help . I was advised Corsa does not supply the clamp. I had to wait 3 days for the dealer to receive the clamp , aftermarket clamps are too cheap and weak , installed the exhaust, started the truck 6.2 liter , found the system is quite compared to a 2017 GMC 6.2 , I called for help 2X , I explained to the lady on the phone that the exhaust sounds like a touring system , she put me on hold so I could talk to a technician, I had to hang up after 18 min , I called back again and the same lady answered , again I was put on hold , exhaust system 14523

2nd system I have purchased, I’m sold on them

Well the system I ordered 14523 did not come with a intermediate pipe clamp, my clamp has broken off even with heat applied. the 3inch clamp is on back order from the dealer. I only use OEM parts , aftermarket clamps are too cheap, so I have to wait another couple of days for the clamp.
