HPi Performance Stainless Exhausts are 100% handmade in-house, in the USA, TIG welded, and feature a perforated stainless muffler interior.

ALL SALES ARE FINAL:
All sales on exhausts systems are final and cannot be returned under any circumstances as they are all custom made to order. 

LEAD TIMES:
Most models have a 8-12 week *minimum* lead time.  If lead time exceeds 8-12 weeks, orders go in the order they were placed.  Note, it doesn't take 8-12 weeks to build one exhaust, the long lead time is due to the amount we have on order, and trying to recover from the National material and labor shortages from the pandemic crisis that started in 2020.  Some of our materials at that time were backordered for a year or more. 

IMPORTANT INSTALL INFORMATION:
After Installing your Exhaust, clean it to remove all fingerprints or residue so that markings do not burn into exhaust system. See below. 

DO NOT NEED TO ADD HARDWARE TO NEW EXHAUST ORDER:
When buying online, you do NOT need to order hardware, clamps or brackets additionally.  The Exhaust will come with everything you need to install.  The extra brackets and hardware are for those who need replacements!**

CALIFORNIA SHIPPING ORDERS WILL AUTOMATICALLY BE CANCELLED: 
If you are ordering online and live in California, your order will be cancelled.  We cannot ship to California.
