Product Details

The Magnaflow 11378 is a high-performance straight-through muffler engineered to maximize exhaust flow while delivering the signature deep, aggressive tone Magnaflow is known for. This dual inlet/dual outlet configuration features 2.25-inch connections on both sides, making it ideal for dual exhaust systems or custom applications.

Key Features:

  • Straight-through perforated stainless steel core for maximum flow and horsepower gains
  • Dual 2.25-inch inlet and dual 2.25-inch outlet design
  • Compact 4-inch x 11-inch x 9-inch oval body dimensions for tight fitment
  • Stainless steel construction resists corrosion and lasts longer than aluminized mufflers
  • Sound-absorbing fiberglass wrap reduces unwanted resonance
  • Reversible design allows flexible installation orientation

Magnaflow's straight-through design eliminates restrictive baffles and chambers found in stock mufflers, allowing exhaust gases to flow freely for improved performance and throttle response. The result is increased horsepower and torque with a deep, mellow exhaust note that won't drone at highway speeds. Built from premium stainless steel inside and out, this muffler provides superior durability and rust resistance for years of reliable service.

Pleasant experience!

It was the first time I bought something from Autoplicity.com and it's exactly what I ordered. Arrived at a reasonable time and put it to good use right away.

Delivery faster than expected.

Thank you foryou fast service, and knowledge. I will definitely be shopping again for my automotive supply needs.

So far so good

super service and best price on the net

Ordering online from Autoplicity was quick and easy.<br>The item shipped quick and arrive a few days later via std ground shipping.<br>The quality and fit of the product (SUV cargo liner) was great, and it made a wonderful Christmas gift!<br>I will purchase from you again, thank you!

Service seems acceptable so far

Excellent service. I called in Monday for a hard to find item which I had ordered from several other online shops who despite saying were In Stock online were not actually in stock at all and the orders were canceled after waiting a week to find out. They had the item in stock as listed on their website and shipped the next day. The price was the cheapest of anyone who actually had the item in stock by a substantial amount.

Thanks for the great service, best prices, and fast shipping!!!
