At HH Muffler, we want you to know exactly what to expect when ordering your parts. Our goal is to process and ship your order within 24 hours whenever possible. Larger, heavy, or multi-unit items (such as mufflers, exhaust pipes, and catalytic converters) may require extra preparation time for safe packaging.
We ship orders Monday through Friday, excluding holidays and weekends. Any orders placed during weekends or holidays will be processed the next business day.
We work hard to get your order shipped quickly. Below is a simple guide for when to expect your package once it leaves our facility:
Orders shipped on Monday
→ Typically arrive Thursday through the following Monday
Orders shipped on Friday
→ Typically arrive the following Wednesday through Friday
Orders shipped mid-week (Tuesday–Thursday)
→ If the estimated delivery falls on a weekend, your package will usually arrive Monday or Tuesday
Delivery estimates shown on product pages and in tracking emails are best-effort projections based on carrier performance. Weather, carrier delays, and high-volume periods may extend transit times.
At this time, HH Muffler cannot ship to the following address types:
PO Boxes
Mailbox-only addresses
APO/FPO or military addresses
Orders placed using any of these address types will be cancelled automatically and refunded.
We currently ship within the United States (including Alaska and Hawaii).
International shipping options may be added in the future.
Shipping costs are calculated at checkout based on the size, weight, and destination of your order. We aim to offer competitive shipping rates with reliable carriers.
Please note: Shipping charges are non-refundable, including:
Original shipping fees
Return shipping fees (unless the return is due to our error or a verified product defect)
This applies to all items, including heavy or oversized parts (e.g., pipes, mufflers, catalytic converters, and full exhaust assemblies).
Some large exhaust components may ship in oversized boxes or require additional packaging. This may result in:
Higher shipping rates
Additional transit time
Carrier-recommended handling procedures
We take extra care to pack all items to prevent damage in transit.
Once your order ships, you’ll receive an email with a tracking number and a link to follow your package’s progress. Tracking may take up to 24 hours to update after the label is created.
