We de-turboed a Sentra. Yes, back to stock it goes to be sold.

A Genesis Coupe 2.0T came in with a cracked exhaust and we not only repaired it but added reinforcements to prevent future damage!

One of our favorite cars came through for a resonator install. We originally fabbed up the intake, air box, and downpipe for this worked Mazdaspeed Protege.

The fabrication shop has been very busy with multiple projects.

We stock VP Racing fuel in all different varieties. Contact us for all your race gas needs!

We just got rid of hundreds of spark plugs that we have removed from customers in the past year alone! A fresh set of plugs will help you get the most out of your tune and we highly recommend a fresh set be installed beforehand, or we can take care of that for it.
