This downpipe kit is a beast! Fits my '19 F350 like a glove and woke up the turbo sound. Easy install, no leaks—totally worth it.

Amazing Sound & Performance Boost – Perfect for the MR2!

Just installed this catback exhaust system on my 1995 Toyota MR2 Turbo, and I’m absolutely thrilled with the results! The 4.5" dual tips look aggressive and fill out the rear bumper perfectly, giving the car a much more sporty and refined appearance.

Perfect Fit & Great Performance

Just installed this downpipe on my Nissan 350Z Infiniti G35, and it works flawlessly! The quality is top-notch—thick, durable steel with smooth welds. Installation was easy, and it bolted right up to the turbo with no leaks.

Noticed better throttle response and a deeper turbo sound right away. Great upgrade over the restrictive stock pipe. Highly recommend!
