Product Details

The MagnaFlow 16717 Touring Series Cat-Back Performance Exhaust System is a complete, direct-fit stainless steel exhaust upgrade engineered to deliver dyno-proven performance gains alongside MagnaFlow's signature deep, resonant exhaust note. Tuned for everyday driving, this system strikes a carefully balanced sound profile — moderate exterior volume with mild interior levels — so you get the performance character you want without fatigue on long drives.

Key Features:

  • 2.5-inch mandrel-bent main piping — keeps tubing diameter consistent through bends to eliminate flow restrictions and maximize exhaust evacuation
  • Dual straight-through stainless steel mufflers — oval 4 x 9 x 14-inch bodies with straight-through, perforated stainless steel tuning pipes wrapped in acoustical fiber for a smooth, deep tone
  • Dual 3.5-inch polished exhaust tips — double-wall, angle-cut, folded-edge design with a 5.5-inch tip length for a premium finished look
  • Dual straight driver-side rear exit — clamp-on connection for straightforward installation
  • Corrosion-resistant stainless steel construction — durable, all-stainless tubing, mufflers, and tips built to last the life of the vehicle
  • CNC precision robotic manufacturing — ensures consistent fit and quality throughout every system
  • 3D scan-developed direct-fit design — engineered for OEM-like fitment with no cutting or modification required
  • Complete bolt-on kit — includes all necessary hardware, resonator, mid-pipe, dual mufflers, tips, and band clamps for a full cat-back installation
  • Dyno-tested performance — independently verified to improve engine power and torque through improved exhaust flow dynamics
  • SAE J1169 tested — meets industry standards for exhaust system performance
  • Made in the USA — proudly manufactured domestically
  • Limited lifetime construction warranty — backed by MagnaFlow's industry-leading warranty against defects in materials and workmanship

The cat-back layout replaces all stock exhaust components from the catalytic converter rearward, making this system a meaningful upgrade over the factory exhaust in both sound and performance. The straight-through free-flow muffler design delivers unrestricted horsepower and torque while maintaining exhaust efficiency. This kit includes all installation hardware needed for a do-it-yourself install.

I was very skeptical of ordering from Autoplicity, as I've never heard of them. They had everything I needed in stock and shipped very quickly, and for a much better price than my normal suppliers at Jegs and Summit Racing. I would recommend them to everyone...............Jeff

The order was placed on a weekend (Order #30758 <br>Order Date: Saturday, September 15, 2012 Order Total: $31.73 <br>It was processed on the first business day. I couldn't ask for a quicker response.<br><br>Good joob all !!!<br>Marty Spellman

Fast shipping, product was excellent .

Very friendly customer service! They also shipped my radiator out very quickly. I will definetly be ordering from autoplicity again!

the only place I could find spacers for my dodge d150 thanks guys!!! hopefully they fit

Amazing !! FAST SHIPPING and GREAT PRICES !! I couldn't ask for better !! I will definitely shop with Autoplicity again !!

I needed a few small XRP fittings for our NHRA Top Alcohol Dragster, I had called XRP and even a "pro racer discount" the price was ridiculous; couple this with their ridiculous shipping/handling charge I had to go elsewhere. I typed in the XRP part number into Google and found Autoplicity, twice as many pcs. as I was planning on ordering and with shipping it was cheaper than one fitting from XRP direct. I will be checking Autoplicity anytime I'm ordering something from this day on, everything about the transaction was smooth and simple. I just got my tracking number today and the stuff is on its' way. Thanks for making this transaction so easy and not robbing your customers on something as frivolous as "handling".<br><br>Respectfully,<br>Brandon Booher<br>NHRA TAD #34

Ordered Thursday, shipped Monday... guess all in all we can't be disappointed. At least they had them in stock.

I build engines for Classic muscle cars and hot rods. Presently assembling chev. SB 383 cu/in. Went shopping for a Name Brand rotating assembly that was complete and ready to install.Shopped several other sites before finding "Autoplicity" Prices were GREAT (best I could find Anywhere), Shipping Very prompt, Shpg. charges Very reeasonable,I will Defenitely use them again!!!

Good prices. Good communication.
