Product Information

Product Details
Part No. 18978
Warranty Details (1 YR REPLACEMENT IF DEFECTIVE)
Featuring 100% aluminized steel for longer service life compared to low-carbon steel, Walker SoundFX direct-fit mufflers deliver quality appearance and favorable acoustics while mechanical interior joints and spun-locked heads provide durability.

Product Features:
  • RESISTS CORROSION -- Aluminized steel construction and internal drainage system helps reduce corrosion
  • BUILT TO LAST -- Internal partitions and mechanically joined tubes allow expansion and contraction during temperature changes to minimize distortion while spun-locked heads and OE-style spot welds provide stability and longer service life
  • EASY TO INSTALL -- Direct-fit bolt-on replacement solution with OE-style hangers, brackets and pipe routings for easy installation that doesn't require specialized fabrication and/or welding
  • FACTORY SOUND -- Louvered tubes help reduce radiated noise for factory-style sound quality compared to straight perforated tubes
  • GET MORE MILES FROM YOUR MUFFLER -- Designed and tested to extend muffler life

Easy to install
I would buy this again.
Verified Buyer - Submitted 5 years ago
Fit perfect I like the fact that the bolts for the outlet flange are welded on unlike the stock muffler. It came without the nuts though, Fortunately I saw other reviews and bought a pack of six (needed 2) before I left the store. That's why I dropped it one star.

what gasket is needed for this muffler

Hi Duffy! Since you didn't mention the specific vehicle, it's hard to tell for sure. To give you the correct information I would need the year, make, model and engine size of the vehicle.
