When you buy a Harley Davidson motorcycle, it comes with a well-engineered stock exhaust (exhaust fitted by Harley Davidson) that complies with all the legal guidelines on pollution and sound emission.
However, many Harley riders are not satisfied with the stock exhaust and want more.
That’s where aftermarket performance exhausts come in.
| Please check laws regarding aftermarket performance exhaust at your place of residence. If your Harley motorcycle is new, check the warranty conditions regarding performance exhausts. |
