Anyone ever heard of SpeedFX Mufflers?
I found an ad in some magazine over the weekend advertising for SpeedFX Mufflers for something around $50 each which seems like a steal, but as we all know sometimes you get what you pay for. I can't find a ton of information online about them online, or even videos on YouTube in action. Best info I've found was in forums saying they're knockoff Flowmaster 40s. Anyone ever heard of these or have any info?
