Product Details

The Magnaflow 15788 Street Series Cat-Back Exhaust System delivers enhanced performance and a deep, refined exhaust note with premium stainless steel construction. Engineered for street-driven vehicles, this complete cat-back system replaces your factory exhaust from the catalytic converter to the rear exit, providing improved exhaust flow and a more aggressive sound without drone.

Key Features:

  • 100% stainless steel construction for maximum corrosion resistance and durability
  • Mandrel-bent tubing maintains consistent diameter for optimal exhaust flow
  • TIG-welded joints ensure leak-free performance and long-lasting quality
  • Street Series design balances performance gains with civilized sound levels
  • Includes all necessary hardware and clamps for direct bolt-on installation
  • Polished stainless steel tips add a custom appearance

Magnaflow's Street Series exhaust systems are designed to provide noticeable horsepower and torque gains while maintaining excellent drivability for daily use. The free-flowing design reduces backpressure and can improve fuel efficiency. This system is engineered for precise vehicle-specific fitment and includes detailed installation instructions for a straightforward upgrade.

I recently needed head bolts for my 408 stroker motor that I'm building. I searched the Internet and Autoplicity had the ARP Head Bolts that I needed. Great price and quick shipping. Will definitely buy from again!!

fine

Mazda cargo mat for the CX-9 SUV came within 1 week. Mat fits perfectly; just as described. Autoplicity had the best price listed for this product; we are very pleased.

Very satisfied! My intake shipped on Friday and I received it on Tuesday. Not only super fast shipping, but a great deal to boot!

Great prices for the springs I got. Def. the cheapest around! Everything was fast and straight forward.

I have searched the internet for the best pricing on auto accessories and ended up at Autoplicity. I tried everything to negotiate prices with some supplies and still got the best pricing usins Autoplicity without any hassles or delays. My invoice number 9314 shows that I got a great deal thanks to Autoplicity. I will be a returning customer for my future purchases.

easy shopping.

Almost a perfect score! I was pleased with the customer service but knowledge about their products warranties was lacking. Other than that, the representative that I spoke with on the phone was great. He was friendly and had a good overall knowledge of the products I was asking about. Pointed me in the right direction because I couldn't be happier with my bike rack. They had the best prices, lowest shipping costs, and my order arrived a day early. Great website to work with. I will definitely be doing business again and spreading the word about Autoplicity.com.

I got all of my parts in and where happy with them. The website is about the cheapest around. Something about them really gives me a good feeling. :)
