National Speed in Richmond, VA, just completed a fairly simple upgrade on my 2019 Camaro SS 1LE that yielded a 100+ rwHP increase. Working with National Speed and Stainless Works my SS produced 461 rwHP on the dyno. The only other mod is a GM Performance CAI. The build is fairly simple and produced eye popping results. Details include:
- Stainless Works long-tube headers - 2.00" primary diameter - 3.00" collector diameter - with high-flow catalytic converters
- Stainless Works axle-back exhaust system - factory NPP exhaust - factory connect - 304 stainless steel construction - Chambered S-Tube mufflers with 4.00" diameter quad slash cut tips
- DSX Flex Fuel kit
- DEI Spark plug wire Protect-A-Boot sleeves
- MSD spark plug wires - 50 ohms/ft - 8.50mm wires - spiral core conductor
- Mishimoto 160 degree thermostat
- HP Tuners
Shocking performance results. And the sound is absolutely sinister. I highly recommend National Speed and Stainless Works. Has anyone had similar results?
