Product Details

The Diamond Eye K3520A is a complete 3.5-inch aluminized steel performance exhaust system engineered specifically for 2004-2012 Nissan Titan trucks equipped with the 5.6L V8 engine. This system fits all cab and bed length configurations, providing a universal solution for Titan owners seeking improved exhaust flow and performance.

Key Features:

  • 3.5-inch mandrel-bent aluminized steel tubing for maximum exhaust flow and durability
  • Precision-engineered mandrel bends maintain consistent pipe diameter throughout for reduced backpressure
  • Complete cat-back system designed for direct bolt-on installation
  • Aluminized steel construction provides excellent corrosion resistance at an economical price point
  • Fits all 2004-2012 Nissan Titan models with 5.6L engine, regardless of cab or bed configuration
  • Manufactured using CNC mandrel bending technology for precise fitment

This performance exhaust system delivers improved horsepower and torque over the restrictive factory exhaust while enhancing exhaust tone. The mandrel-bent construction ensures smooth transitions and consistent pipe diameter, eliminating turbulence and allowing exhaust gases to exit more efficiently. Diamond Eye's aluminized steel construction offers long-lasting protection against the elements while keeping costs reasonable compared to stainless steel alternatives.

Title

Diamond Eye Performance 2004-2012 NISSAN TITAN 5.6L (ALL CAB AND BED LENGTHS)-3.5in. ALUMINIZED-PERFORMA

I have a 2009 Nissan Titan Crew Cab Long Bed and the fit of the product was pretty descent. I found getting the muffler level to be a bit of a chore, and the placement of the front dual clamps to be a bit wonky (left side and right side pipes bolt to the catalytic converter and come together at he muffler and there is a support bracket that has two exhaust clamps welded on it and these clamp the pipes to the muffler inlets). It wasn't a big deal, just took some fenagling. I was concerned that the larger pipe diameter was going to translate into cab noise, but I found it to be moderately quiet and was pleasantly surprised. It does over a nice low rumble tone, but its not over bearing. The instructions lack a bit in that there is an extra pipe for the Crew Cab Long Bed that wasn't part of the part placement diagram. This is the second Diamond Eye Exhaust system I've purchased, one for the Titan and one for a 7.3L PowerStroke Ford. The price point is really good, and I have been very pleased with both products. Ill be purchasing a 3d for my Nissan Armada. You cant go wrong.

The best price for the best parts I'm looking for; trusted site A+

Easy and cheap, thanks for your service!!

The best prices and fast shipping!

Lowest prices as far as I could find on the internet that shipped to Hawaii. Seem very reliable and good on updating you on the status of your order.

Easy store to navigate through and had all the info.

if this is the right part, I will be very pleased

Easy site to use and order from. Autoplicity has friendly customer service and also they had the CHEAPEST price on the exhaust tip that I ordered for my truck. I am a very happy customer!!!

I have used them a couple times. Always seem to be one of the lowest prices on the internet and pretty quick turnaround on shipping. If you live near Los Angeles, they have a warehouse in Cerritos, so things arrive real quick once they're shipped.

Purchased an item that was cheaper here than any where else. I made the transaction through Amazon. I got confirmation that I made a purchase, but nothing ever stated the charge was made. I did not get confirmation of shipment either. Sent email, requesting charge/shipment. I received shippind g confirmation and delivery same day. I made purchase on a Sunday and received item on Wednesday. Great prices, and very fast shipping...just would like to have known all was well with order etc.<br><br>I would recommend this place and will look here again for price check...
