Not Ranked
Sparks,
Actually, changing out the mufflers on mine was probably some of the best money I've spent. I have before and after dyno's, and it is actually the cheapest horsepower you can "free up". Many people here do all sorts of expensive engine mods to get marginal gains in hp, but you still end up forcing it through your 2" core. When I changed out my mufflers, it changed the whole demeanor of the car for the better. I mean a completely different car from 2100 rpms and up in that the entire power curve was moved up.
Another thing is that I've cut out a few factory muffler cores, and all of them had the welds on either end cracked to where the center pipe was free to collapse and restrict even more flow.
Finally, a 3.5" core ain't better than a 3" core.
