Cons Of Straight Pipe Exhaust System

1. Excessively Loud

The extra noise that emanates from the exhaust system is less likely to be something many motorists would like, as the noise that can be tagged as “deafening” which the exhaust creates can make driving in many authorities illegal. This restricts you from making use of the car at other places — with exception of the “racing tracks.”

Using a standard straight pipe exhaust system, a 100 decibel sound racing mark can be surpassed without hassle, as there’s not a single sound dampening mechanics or mufflers, giving out the noise the engine created. For people who are inside the car, it can be quite unpleasant hearing the sound of the exhaust — if you’re not putting on earplugs.

Another disadvantage of this very system is that when you carry out an emission test on your car, it’s very much likely to fail.

3. Expensive To Install

It’s quite expensive to get a straight pipe exhaust system, so it’s necessary for you to make up your mind when it comes to getting it for the car you drive. In many cases, the vehicle requires a total revamp of its exhaust structure in order to find a way to accommodate the new pipes, and if you make use of top-end pipes, you’ll spend a little less than $1,000 on only the pipes.

If you find the need to buy the installation kit and parts only, and you plan on performing the installation yourself, then get prepared to spend thousands of dollars before you even complete the process.

4. Can Make The Vehicle Harder To Sell

If you have plans on reselling the car you drive, in the future, a great idea would be to erase the thought of changing your standard one. It’s illegal to setup the straight pipe exhaust system in a lot of places — you may have to take out the entire thing in order to sell the vehicle. Even if you come in contact with someone who doesn’t have any issue with the setup, it is highly probable that they will offer you less money for it as they will eventually have to replace it.
