Performance Exhaust Buying Guide

Just so you can get hold of the right aftermath exhaust system without having to probe through each option, many of which promise fake claims, consequently wasting your bucks, here is why we have assembled a guide for you that offers the “all you need to know” information about the item in question.

Tubing

If you reside in dry areas, then prefer aluminized tubing. But if in areas with high moisture in the air and uses road salt, then stainless steel tubing should be corrosion resistant like the T304 stainless steel. Replacing stock tubing with free-flowing mandrel tubings ensures that maximum horsepower is gained out of your engine for optimal performance.

Loudness

It is better to gauge how loud your system would be once installed before the constant droning becomes obnoxious and starts assaulting your ears on long rides. Therefore, check the sound clips offered online from the manufacturers.

Modification Requirement 

Though many exhaust systems are easy to install with bolt-ons and require no alterations. There might be kits that would require minor welding to be the perfect fit or new exhaust gaskets, both of which will be found in product descriptions usually.

The Magnusson-Moss Warranty Act

To ensure that your dealer doesn’t nullify your exhaust system warranty once you have installed it, there is the Magnusson-Moss Warranty Act that will prevent them from doing so. There are many manufacturing defects that come in the picture only after installation, so this act ensures the warranty of your repair and/or exchange. Unless the fault was not manufactural but on your account.

Header and Axle-Back Systems

Once you have determined how much tubing you want to barter, you can then choose either header or manifold back exhaust systems, which though can be labor-intensive and might require a mechanic for installation. Or pick Axle-Back system, which readily replaces the easiest parts of OEM (original equipment manufacturer) exhausts to access elevated levels of horsepower, acceleration, and sound.

Conclusion

Though you really don’t ‘need’ an exhaust system, with cruisers like Harley having their potential limited but still offering optimal performance at the factory. But we all prefer getting every ounce worth our dimes.

With options like full-system and slip-on mufflers, out of the two alternatives, it is the slip-on that is more budget-friendly. However, the slip-on has minimal effect on boosting engine performance. It is the full-system that offers guaranteed optimal horsepower, torque, and fuel efficiency despite being on the pricey side.

After doing thorough knee-deep research, we narrowed down our findings to the above mentioned 9 motorcycle fuel stabilizers that are not only budget-friendly but also don’t cut back on efficient performance. 

So we suggest that once you find one who beats or meets your criteria, don’t check it off if it doesn’t come in your budget range. Spending a wad just to cry out loud, in the end, wouldn’t be ideal. Therefore, instead of going for cheaper alternatives, we suggest that you save up and then make the purchase. We are sure you won’t be disappointed, you can take us up on our word!
