Immaculate welds more like art then a part

The level of craftsmanship and beauty on these downpipes are absolutely incredible. Im waiting on turbos before I install them but im happy with my purchase even just looking at them.

I love these secondary catless down pipes! I can definitely feel the extra power due to there being less restrictive exhaust flow and less back pressure. The turbos are spooling up much faster and there is less turbo lag. I also like the aggressive rumble from the exhaust at WOT! My EGT's and Waste Gate Duty Cycles are also lower as well. The pipes look and feel premium and are extremely lightweight! Definitely worth every penny!

Awesome fit. Dave from BMS recommended cmbuilds and I've been following cmbuilds for a while so I knew I had to grab the mid pipes. Sounds like how the car should have sound from manufacturer

Great quality and very easy to install. They give your 3.3 a deeper tone especially if you already have a cat back exhaust. Also sounds great under load!

Very nice and make my car breathe better more performance

Amazing quality. And great customer service. You can never go wrong with CMBuildz.

Cm Buildz is the best in the business

I just installed the Stinger/G70 down-pipe on my Kia Stinger and I couldn’t be more impressed — the build quality is top notch. The materials feel premium, the welds are clean and precise, and the fitment was spot on. It’s clear this wasn’t an off-the-shelf part thrown together — the craftsmanship really shows.

On top of that, I also grabbed one of their “Daily Grind” T-shirts. I’m surprised how solid the tee is: thick cotton, great stitching, and a comfortable fit. It’s rare to see the same brand nail both performance hardware and lifestyle gear.

Overall every aspect of the purchase exceeded expectations. If you’re looking to upgrade your Stinger’s exhaust/down-pipe and want something that’s well made and backed by a company that cares, I highly recommend CMBUILDZ.

Excellent fit no issues whatsoever, they look amazing in person. The guy at the shop was very helpful answering all my questions. Definitely recommend

10/10 Quality

High Quality, perfect weld, best ones hands down for the platform. Highly reccommend.

This fuel pump is a beast in a small package. I installed it in my 2023 WRX and noticed the difference immediately. Fuel delivery is smooth and consistent, even under heavy boost. DeatschWerks nailed it with this one—perfect for high-performance builds that need reliability and flow.

This -20AN bulkhead fitting is exactly what I needed for my custom fuel setup. The aluminum is top-quality, threading is clean, and the black anodized finish adds a professional look. No leaks at all. Highly recommended for any high-performance build.

I installed this Mishimoto hose kit on my 2008 Titan, and the improvement is noticeable. Not only do the hoses look amazing in red, but they also feel way more durable than the stock ones. Fitment was perfect, and it came with all necessary clamps. No leaks, and my engine runs cooler.
