Rod knock is the sound of your engine hitting the pistons. It’s caused by a build-up of carbon deposits on the piston rings, which then causes them to wear down and become loose. The resulting friction causes an audible knocking noise, which can be heard when you accelerate or decelerate quickly.Rod knock can also be…
I was about to buy an expensive set of long tube headers. Their horsepower boost, along with a booming sound, convinced me to buy them. Nevertheless, a friend of mine suggested reconsidering the decision since I live in a state where these headers are not legal. Long tube headers are illegal in most states in…
One of my buddies couldn’t decide what header to choose for his heavily modified car. He was intrigued by 1-7/8 headers but questioned whether the extra cost was justified. After reviewing his car and seeing its potential for power, I strongly suggested upgrading to a 1-7/8 header. And why is that? The 1-7/8-headers will be…
I see many car owners concerned about their headers getting too hot. How Hot Do Headers Get? The truth is that headers are expected to heat up. Having said that, you should ensure that the header’s temperature does not exceed a certain point. For that, it is necessary to understand temperature profiles under different driving…
I experienced a dramatic increase in power after I installed headers on my exhaust system. However, over time, I noticed that the extra power was diminishing. So I immediately jacked up my car and checked my exhaust. Soon, my eyes caught sight of the stains and rust build-up on the header. Thankfully, cleaning them fixed…
Test pipes have almost nothing to dislike. In addition to the affordability, they are incredibly easy to install. However, one thing I was skeptical about was whether this pipe would increase a car’s horsepower. So I began using test pipes for a more thorough investigation. And guess what I discovered? The pipe indeed improves horsepower,…
Looking at the features of test pipes and downpipes, you would assume they are the same. One of my neighbors had similar thoughts and bought a downpipe without thinking twice about it. Now he regrets the decision as a test pipe would have served his purpose far better. Test pipes and downpipes differ primarily in…
If you want to make your awesome car louder and stronger, then modifying the exhaust system is the ideal way to do so. Resonated and non-resonated exhaust systems work differently. So, it is obvious that resonated and non-resonated j-pipes offer different performances as well. The key difference between resonated and non-resonated j-pipe lies in their…
If you’re a car enthusiast, you’ve probably wondered if test pipes make your car louder. While they don’t necessarily make your car sound better, they can make it louder. Test pipes remove the catalytic converter to make cars sound louder. As the cat is no longer present, the sound is less muffled, which results in…
