  1. To be fair, your own testing indicates some of those claims to be accurate, at least in a few cases. The of the TIP is a pretty clear example. The downpipe as well, if you are willing to remove the catalytic converters and go to 3″. But I do agree that most of the “restrictive” claims made by most aftermarket manufacturers are exaggerated or false.

    1. I get a chuckle from the non-descriptive use of the term restrictive. Any part is going to create restrictions, including all of those aftermarket parts. Saying that a part is restrictive is stating the obvious in a vague way that is done to imply superiority of the alternative being offered for sale without providing the consumer with useful information to decide if the purchase is justified.
