‘Absolutely amazing experience. Scott and the whole team were very professional and explained every part of the process.  Communication was superb and they answered all of my questions very promptly.  The Blackwing runs better than ever and feels like a completely different vehicle.  They are the LF4, LT4 specialists and can back up their performance gain claims with hard data.  I easily got a 100 hp boost to the wheels after their blue belt performance package.  My only regret is that I didn’t go to them sooner!’

Every day we get requests for CT5-V 3.0 liter LGY engine downpipes. You asked and we listened…

Our new CT5-V downpipes design has been completed and the first batch is in production now. These are made in the U.S., fit perfectly and sound fantastic. Gesi brand 400-cell EPA compliant catalytic converters are included standard. The test car has ~ 150 street miles with no Check Engine light. Dyno numbers are not yet available. We’re currently accepting pre-orders, and plan to ship in early March.

Special thanks to Stephen N. for volunteering his car to make these downpipes a reality.

Vince dropped by with his 2023 CT4-V Blackwing for the Purple Belt treatment. Since his car had the A10 transmission, we worked with HP Tuners to unlock and tune both the ECM and TCM. We provided Vince with two custom tunes. The first is his ‘daily’ tune, which constantly reads alcohol content and automatically scales fueling and ignition timing, producing 516 whp on 93-octane pump gas and 571 whp on E60 or higher. The second is his ‘kill tune’, which has boost and timing both cranked up. This tune produces a peak of 614 whp.
