A brand new Rapid Blue 2020 Corvette with just 20 miles visits Late Model Racecraft in Texas for installation of LMR’s high-flow Catback exhaust, but first, it hits the dyno for a baseline test.
This new video from the Texas tuner shows that LMR can basically install their Catback exhaust system in about a day’s work, not including the dyno tests before and after.
One of the interesting “finds” in this video is that we learn what the top speed of the C8 Corvette is if you have the Front Lift engaged. The Rapid Blue Corvette was lifted by one tech as it was maneuvered onto the dyno, but the tech didn’t lower the car after it was all strapped into place. During the dyno test, the Corvette was speed limited to only 102 mph and as they attempted to figure out the cause on the second run, we see the alert on the Drivers Information Center. After realizing the Front Lift was engaged, the car is lowered back into regular driving posting and then the baseline dyno test is able to be completed.
Next up is the install of LMR’s high-flow Catback exhaust system for the C8 Stingray. A time-lapse video shows the technician prepping the car and then beginning the teardown process to remove the factory system. Then the new exhaust plumbing and mufflers are installed and after ensuring that the exhaust tips are centered correctly, the rear fascia is bolted back on. Finally, the car is started to make sure that it runs correctly and that there are no exhaust leaks present.
We get a few sample revs from the newly installed exhaust and it does sound deeper than the stock Tenneco exhaust system that was removed. The car is then returned to the dyno bay for its post-install test. The Corvette originally dyno’d at 437 rwhp and 419 lb-ft of torque. Following the exhaust install, the new figures were 459 rwhp and 441 lb-ft of torque.

We get a Rapid Blue C8 delivered to us straight from the dealership with the intent of receiving our complete exhaust system which includes high flow cats and our Catback exhaust! Our system not only makes these cars sound like true sports car after install, but you also gain a solid 20rwhp and 20rwtq across the powerband.
