Review on Walker 18238 SoundFX Muffler by Evan Burnside

I ordered this to replace the factory muffler on a 1978 Ford F150. The intake was a perfect fit (factory exhaust is 2" OD), but the exhaust (factory exhaust is 2 1/8" OD) required a small modification. I had to bend the muffler outlet to just over 2 1/8" ID to fit the factory exhaust. Overall installation was easy and the whole process took less than 15 minutes from start to finish, but I got lucky. Hold those Proper tools on hand to change the outlet port on the muffler Sounds good at idle (at 4.9L/300cid 6cyl) and does what it's supposed to do I would buy it again if I had to replace this one.
