|Okay, so there's one thing that everyone reading this is starting to ask, which is, “What about power?” While many people go with an aftermarket cat-back exhaust thinking that they're going to gain 20+ horsepower at the wheels, I'm here to tell you that's not going to happen. If you're doing headers, removing cats and doing a straight-through system all the way back, maybe, but even that's a stretch. What you're really getting with an exhaust is weight reduction, looks and sound, with a side effect of a slight power gain. We were curious, though, so on the dyno we went…
|As we said, there simply isn't a lot of power to be gained with a cat-back exhaust alone, but there are gains nonetheless. Based on the dyno graph, you can see that we had pretty much the same gains across most of the rev range, so there's not huge peak gain, but it's a decent gain across the board. Our baseline numbers maxed out at 141.1 whp and 142.9 wtq. Post exhaust work we managed 146.8 whp and 149.5 wtq, so nothing out of this world, but considering it's our first and only power upgrade so far, it's not that bad at all. It's definitely got us looking forward to seeing how much more our little M52 has to offer.
