Bolt ons and no tune?
Is it safe to install bolt ons (test pipes, y pipe, mid pipe, and exhasut) and drive casually (under 3k rpms)? Will the CEL come on because of the differenice in AFR? I don't have any aftermarket CA I yet, but I plan on getting them some time down the line. I am thinking of installing the parts listed above and am waiting a week or two until I get an ecutek tune.
