OEM Exhaust Mod Questions

gulewamkulu · 03-26-2018, 09:48 AM

A friend is willing to help out with the OEM Exhaust Mod, but had a few questions:

- Size - I gather 2.5 " is the commonly used size, but please confirm. Also, what length of pipe would I need for a 2 pipe mod?
- Do you guys use Stainless; Austenitic (Non magnetic) or Ferritic (Magnetic), or a higher grade Carbon Steel?

Your feedback will be greatly appreciated.

Peter.

1- Diameter is 63.5 mm or 2.5 Inch .
2- Stainless Steel.
3- +/- 50 cm or 19.5 Inch is more than enough.
