LS3 S13 Smoke Machine - Brendon Keating

"I first got into contact with Paul with my S13 LS3 build. I contacted him regarding a custom exhaust manifold I needed to complete my swap. The customer service is awesome. My goal for the manifolds was to have them able to be removed easily and without pulling the steering shaft. Paul and his guys fabbed up a perfect fit manifold meeting all my goals and then some. From there I decided to get the full exhaust system front to back done.  They managed to fit 2 high flow cats, resonator, and muffler with awesome fitment as well as a track only straight pipe that looks as good as it functions.  The first shakedown with the car was excellent. Running the grassroots oil cooler the ls3 was unstressed and oil had stable temps throughout the weekend. From custom fab to custom parts, Grassroots is a one-stop shop. I'm excited to try out some more parts that Paul and the crew at Grassroots have to offer."
