    255-24904 is rated 4.0 out of 5 by 1.
    Rated 4 out of 5 by from Good exhaust, but loud! Hello all. I have a 2009 Silverado 1500 Crew Cab 4wd with the 5.3L LC9 engine. I recently had some work done on the valve train because of some damage that was found on a couple lifters/cam lobes. In total, I had a mild cam installed, new lifters/push rods/springs/trunnions, upgraded the oil pump to a higher pressure pump, and had them do an AFM/DOD delete. I also installed a K&N 77 cold air intake, Kooks long tube, 1-3/4" headers, Kooks catted y-pipe, and wanted to finish the exhaust off with this Corsa dB cat-back. First off, the install was pretty simple. After removing the stock system, hanging the Corsa system was really easy. Since everything clamps together, I highly recommend picking up a $6 tube of exhaust RTV to apply to all the clamped pipe sections prior to tightening the clamps. My exhaust installer didn't do this on the clamped sections of my Kooks y-pipe and they leaked. If you have the extra coin, and want some permanence, you could also just have the whole system welded into place by a muffler shop....I didn't want the permanence of a welded system, so I stayed with the clamps. This was all pretty easy, but the hard part came when I tried to connect the Corsa cat-back to the Kooks y-pipe. Both systems (the Kooks and the Corsa) were designed to meet up to the original spherical clamp location just behind the y-pipe. So, whether you had a Kooks y-pipe connecting to the stock cat-back or a Corsa cat-back connecting to a stock y-pipe, either way would connect with no problems. I found out the hard way that despite both systems connecting individually to the stock counterparts, the Kooks y-pipe and Corsa cat back didn't mesh up to each other enough to actually clamp them together. The dimensions were perfect, and they met in the proper location, but the overlap on the clamping location was too short to be able to apply a clamp to get a good seal. Obviously, the Corsa system isn't designed to specifically mesh up to a Kooks y-pipe, but I figured since both were compatible with stock, they'd also be compatible with each other. So, this was my first hurdle. I solved the problem by cutting out the spherical clamp sections, and bridged the connection with a 3" to 3" coupler that I bought from the local auto parts store. The swing in the rubber exhaust hangers allowed for enough play in the cat-back to install the coupler without having to unbolt the headers or take the cat-back out from the hangers. Before installing the coupler over the pipes, I applied a little bit of exhaust RTV to aid in sealing the pipe connections. I then sealed everything up with some 3" u-type exhaust clamps I bought at the auto parts store. After finishing, I figured this set up was actually a little better (other than a little extra work) because the pipe I used to bridge the gap had a 3" i.d. as opposed to the 2.75" i.d. of the original spherical clamp section. (Since both systems were designed to be in front or behind the stock systems, the spherical clamp sections of both systems necked down to the stock diameter in order to meet the stock connection). So, instead of having a 3" exhaust with a 6" section of pipe that was 2.75" i.d., it was now 3" i.d. from the y-pipe all the way to the exhaust tip. Now that I was done, it was time for a test drive. After starting the truck, everything was perfect. There were no leaks from front to back, and the truck had a mean growl. With the mild cam and LT headers, it had a slight lope that sounded awesome. There was a warning on the directions of the Corsa cat-back that the system would be slightly louder from a cold-start than it was after warming up. This was definitely true. The truck quieted down a bit after warming up. Once the truck was at operating temperature and I had a back-road section of straight road, I came to a stop and then let 'er rip. HO-LY COW!!! This system is so loud at WOT. Obviously, with any performance exhaust upgrade, the sound is going to be louder than stock, but this was a whole other level. I'm not saying that this is necessarily a bad thing, but it's definitely worth mentioning. My wife drives the truck throughout the week as a daily driver, and she wasn't super happy with the new exhaust. Prior to the Corsa cat-back, I had the Kooks headers and y-pipe connected to the factory cat-back. This was very tame, but I hated the idea of the 2.75" stock exhaust and restrictive muffler. The solution to the loudness was I cut out the 3" coupler I installed and replaced it with a Vibrant Ultra-Quiet Resonator (Vibrant part # 1142). This was the PERFECT combination. The truck still sounds mean when you put your foot on the floor, but it is much more tame at the cruising and light-duty acceleration/speeds. To me, it's the best of both worlds. I still have the free flow of a 3" mandrel-bent straight-through exhaust system, but it's tame enough that daily driving/light duty applications are must more tolerable. All in all, I review this product as good! The price is much cheaper than the Corsa Sport line of cat-backs and it definitely sounds great. For my purposes/comfort, I installed a resonator to take the edge off, but that doesn't mean that it's a bad system. Given what I've said thus far, another thing to take into consideration is the many factors that affect exhaust sound. Trucks that have the stock exhaust manifolds/cats/y pipe may sound COMPLETELY different with this system installed. Also, trucks that have the stock cam may sound different, too. Lastly, since my truck has a DOD delete kit installed, I can only comment on how this system sounds in V8 mode, as my V4 mode has been completely removed. Therefore, as far as sound is concerned, my truck has almost all the major modifications that produce MORE sound. From the headers, to the high-flow cats/y-pipe, and even the CAI, several of the stock parts designed to reduce noise have been removed. As such, take this review with a grain of salt. If your truck is set up exactly like mine (5.3L, mild cam, DOD delete, headers, catted y-pipe, etc.) this review will tell you a lot more than if you had a truck with a different configuration/modifications. One last thing I want to mention is the difference between the Corsa db and the Corsa Sport as far as drone is concerned. The Corsa Sport systems GUARANTEE that there is no drone at any speed, ever. This same guarantee does not exist on the product information page of the Corsa dB. Therefore, I guess that means there is a chance for droning with this system. After extensively paying attention to the exhaust note at different speeds/RPM ranges, the only place I would say this system even has a slight drone is at 1600-1900 RPM. If you have the stock tire size, a 6 speed transmission, and 3.42 gears, this RPM range is coincident with 60-70mph. It is very faint at 60, gets noticeably worse as you approach 67-69mph, and fades away quickly beyond 70mph. I cruise at 80mph at exactly 2000rpm and it is completely gone by that speed. These RPM ranges are in 6th gear. I notice the slight drone as I accelerate through 1600-1900 RPM in gears 1-5, but since that RPM range isn't constantly maintained until 60-70mph, it's fairly unnoticeable. Again, take this information with a grain of salt. Droning is a function of resonance, and many factors influence resonance. The length of your truck can make a difference, whether you have all the mods my truck has makes a difference, and then of course the speed/RPM numbers will be different in your truck if you don't have a 6 speed transmission, stock tire size, and 3.42 gears...all of these factors can affect drone. So, take that as you will. One last thing.....I had a hard time finding details about what type of stainless steel this system was made from when I was deciding on an exhaust system. Just to be clear, this system is, in fact, 409 stainless steel-it says it right on the piping.
