Product Details

The Dinan High Flow X-Pipe is a performance exhaust upgrade engineered specifically for 2015-2020 BMW M3 and M4 models. This midpipe section replaces the restrictive factory resonators between the catalytic converters and rear muffler, unleashing more aggressive exhaust tone and improved flow characteristics.

Key Features:

  • Premium 100% 304 stainless steel construction for durability and corrosion resistance
  • Upgraded 2.75-inch (70mm) mandrel-bent tubing replaces stock 65mm hydro-formed pipes for maximum flow
  • True X-pipe crossover design made from mandrel-bent tubing, not stamped components, for minimal restriction
  • Complete resonator delete for enhanced exhaust note and reduced backpressure
  • Direct bolt-on installation with all necessary mounting hardware included
  • Engineered and tested by Dinan for precise fitment and performance

This exhaust component delivers noticeable improvements in throttle response and a more aggressive exhaust sound while maintaining Dinan's reputation for quality and precision engineering. The mandrel-bent construction ensures smooth, consistent tubing diameter throughout all bends, eliminating flow restrictions common in crush-bent alternatives.

I just received my order, I was expecting it on Saturday so that was a nice surprise. I will have to install it in my car and then finish my comments. Then I will let you know the rest of the story. Thank you.

Products have a good price but shipping is expensive. Two light bulbs $10.00. That is crazy.

best prices I've found for quality shocks

good

First time shopping with autoplicity. Competitive pricing, free shipping. Parts delivered on time. Unfortunately experience with subsequent order wasn't as good.

Ordered Monday - didnt ship until Thursday.<br><br>Email sent tracking number, but didnt mention which source was used for transport.<br><br>Product as described.

I ordered this Weathertech cargo liner (order#: 8049) on a Tuesday and received it by Saturday. Speedy delivery and absolutely love this product. It is a perfect fit and still easy to get to the storage compartment of my Rav4.

Purchased K&N Filter. Excellent price and received filter as scheduled.

Best Price around. Ordered Friday Shipped Monday. Thanks
