Product Details

The MagnaFlow 17137 Off Road Pro Series Cat-Back Exhaust System is engineered for off-road and performance gas-powered applications, delivering an aggressive exhaust note and improved flow over the restrictive factory system. Constructed entirely from premium 409 stainless steel, this cat-back system is built to withstand the rigors of off-road use, resisting corrosion and heat fatigue season after season.

Key Features:

  • Full stainless steel construction for long-lasting durability and corrosion resistance
  • MagnaFlow's signature straight-through perforated core muffler design for maximum exhaust flow and reduced back pressure
  • Deep, aggressive exhaust tone tuned specifically for the Off Road Pro Series
  • Mandrel-bent tubing preserves consistent inner diameter for unrestricted exhaust flow
  • Includes all necessary hardware, hangers, and clamps for a complete installation
  • Direct bolt-on fitment — no cutting or welding required
  • Designed to meet or exceed OEM quality standards

The MagnaFlow Off Road Pro Series Cat-Back system begins at the catalytic converter outlet and replaces all downstream exhaust components, including the muffler and tip(s). This makes it a straightforward upgrade for enthusiasts looking to improve exhaust performance and sound without modifying emissions equipment. Backed by MagnaFlow's reputation as a leading manufacturer of performance exhaust products made in the USA.

Ordered a couple of items. The first was a air intake kit. I had put in all my info for my truck and chose one from the list to order. Won't fit. Called to tell them and they asked if I had called manufacturer...ummm no. Said I needed to contact them to verify wrong part. They were closed, so went to website. The part they sent me was a universal fit- for cars, not trucks, but did find right model- $90 more. Called back autoplicity and was told I need to go through email to get an RA# to return wrong part- site says I can call. Been on hold for over 20 mins and still waiting. Hope the Nerf bars I ordered fit! Update- they called me back, got my RA#. Very pleased with how Nick handled things- it was what I expected the first time. He verified the NERF bars will fit and will be changing the website so the universal intake does not show on list for vehicles with larger air outlets. Changing my rating to show my satisfaction with how it was eventually handled.

Lowest prices of what I was looking for and super fast shipping!!

Everything was great just the returning could use help. The first ine i ordered was wrong and shipping back to you is more costly than i hoped.

Great company best prices around and would highly recommend

Product was a good price, fast shipping and great costumer service! will do business again!
