Muffler Delete Question
I've been searching for a while now and a muffler delete either loses power or gains power. No clear answer, and from my understanding, the weight loss from the stock muffler removed and the slight power decrease from the muffler delete makes it equal to stock, performance wise.
I've been running around without my muffler for a while now and I personally don't see a loss in power. I daily drove the car with the stock exhaust for about 5 months and then when I got a proper daily I took the exhaust off to see what it was like. I'm in love with the sound but I'd rather get something that benefits me power wise as opposed to dropping $200-$300 on just the sound. As far as drone is concerned, it's there with the top up, inexistent with the top down so I'm really not bothered by that. I just want it to be faster. So. With that said, what's the deal? What's the definitive answer? And also, if it loses power, how do the aftermarket applications differ? Wouldn't a less restricted exhaust flow be more beneficial? I truly apologize if the answer is hidden in the mountain of posts about this question but I just haven't found the clear-cut answer yet.

There is no loss in power. The ones claiming there is truly don't understand backpressure vs. scavenging.

So one more question, is the scavenging effect only useful for low end power? Is it there for a better overall powerband or is there another reason as to why you would want the scavenging effect? (Apart from the ones mentioned in the website)

The myth of back pressure being necessary probably came from some guy thinking bigger was better, so he put a massive fart can on his Honda and noticed a power loss at low rpm. While there was indeed less back pressure, there was also less scavenging, and the power loss was incorrectly blamed on the loss off back pressure. There is no one size fits all exhaust setup. You choose where you want to maximize efficiency. Stepped headers are a compromise between scavenging and flow, but they are still a compromise.
