Read on to learn more about the process of conducting a muffler Delete, as well as the pros and cons associated with such a modification.
What Exactly Is a Muffler Delete?
A muffler delete is a specific type of exhaust system modification, through which a vehicle’s sound muffling apparatus is intentionally removed.
In most cases, the process of completing a muffler delete involves removing the muffler itself, before replacing the stock component with bypass tubing, complete with one’s exhaust tip of choice. Modifications of this type are often done in combination with a resonator delete.
While some muffler deletes are accomplished through the use of a specialized kit, others are done by basic means, using “straight-pipe” tubing, with an affixed exhaust tip. The installation of this replacement hardware can be done by using specialty exhaust clamps, or more permanently, by welding the replacement hardware in place.
No matter one’s preferred method of completing a muffler delete, it is important to consider the legal ramifications of making such exhaust system modifications.
In some states and municipalities, modifying a vehicle’s stock exhaust in any manner is illegal, and can land you on the wrong side of the law. This, in turn, can yield hefty fines. Therefore, it pays to know the law before deleting your vehicle’s muffler.
Additionally, it is also important to consider that carrying out a muffler delete can void your vehicle’s warranty. In many cases, manufacturers leave such decisions up to individual dealerships on a discretionary basis.
Therefore, unless expressly mentioned in the terms of your vehicle’s warranty, you might find yourself at the mercy of the dealership, when attempting to keep your warranty coverage intact.
