We’ve noticed with the arrival of the 2020 Corvette that the custom exhaust business is alive and well. We’ve seen a couple YouTubers working on solutions including this solid-sounding system from MagnaFlow. Joining the fray in creating a custom exhaust for the 2020 Corvette is Texas tuning shop Late Model Racecraft who shared this new video as they put their custom Catback exhaust to the test on the dyno.
LMR says their main goal for the system was to change the sound pitch and they got exactly what they wanted. But the big surprise for them is that while they expected a modest 5-8 horsepower gain, they saw increases as high as 20 hp and 20 lb-ft of torque across the board.
LMR describes it as a 3-inch stainless steel system with a custom X-pipe going to 4-inch dual tips, and this Corvette still has the factory catalytic converters, but LMR says not for long!
Here’s a post they offered on the Corvette Forum about the exhaust system:
This is a 3in stainless steel system with a custom X-pipe going to 4in dual tips. We actually did not expect to see this much gain under the curve. Honestly, a gain of 5-8hp is what I was expecting at most because the stock muffler works like a cutout(straight through) with the valves open. My biggest goal with the CATBACK system was to change the sound pitch and IMO we accomplished the sound I was looking for perfectly. You can see it still made almost the same at Peak HP at higher RPMs. It really shows a good gain in torque. We are going to try a set of high flow cats next and will share those results as well.
Late Model Racecraft is planning on offering their new system for sale once they’ve finished testing it so if your interested, you can contact them through latemodelracecraft.com.
