Clearly states in their warranty not to use unauthorized aftermarket parts with their stuff.
"The Dinan Limited Warranty Specifically Excludes:
Damage resulting from the use of other manufacturer’s products in conjunction with Dinan products or systems."
Just gives them a good reason to deny your warranty claim.
The reasoning for me to get the Dinan tune would be to keep my engine warranty intact after a ECU tune. I'm sure Dinan would not cover any emissions warranty concerns if another manufacturers exhaust system was used. However, I don't see how aftermarket pipes would affect engine components.
