These are not your ordinary mass-produced exhaust pipes. While we may have the pipe you want in stock and ready to ship, most Sawicki Speed exhaust systems are made-to-order and handcrafted.

Polished and ceramic coated systems require additional production time as we must send these out to receive their finishes. Here’s what you can expect:

  • Brushed Stainless exhausts typically ship in 2-3 weeks
  • Mirror Polished exhausts typically ship in 4-6 weeks
  • Jet-Hot Ceramic Coated exhausts typically ship in 6-8 weeks
  • Our new RT Shorty exhausts will ship in 4-6 weeks.

In the words of our customers, “It’s worth the wait!”
