So I've only had these for a few months but these were the nicest sounding test pipes I could find, they sound just like art pipes and they have the same quality as z1 motorsports exhaust components, they perform way better than cats and sound as good as high flows if not better and they don't pop codes. Easy to install and ready for header paint out of the box, they come with all hardware and they look like they mean business. No fitment issues, just hammer the studs above them before install.

I haven’t installed them yet but they seem to be high quality and I know that there stainless steel the welds are also nice

I love conceptzperformance. Spoke with Nick and he helped me with my order. Knowledgeable and friendly love talking to those guys that concept Z. Took my order a couple hours ago and it’s already shipped out. awesome

Description

The result in using Helmholtz resonated chambers is a quieter, deep and smooth V8 like sound for the VQDE and VQHR engines, while getting rid of raspiness and dronning. The TORQEN HELMZ test pipes come with 24 months warranty for the initial customer and that covers fitment issues, welding defects or deep rust.
