Midpipe Alternatives

Ok so I've a jb4 on my car and am currently running map 1, what I know is that with a more free flowing mid pipe I will be able to run map 2, Ive heard of the Dinan resonator delete but I wanted to know if there were any other companies I making mid pipes that are separate from a full exhaust.

As far as i know the stock midpipe does not (or just a low amount) generate backpressure since its just e resonator. You may want to get an aftermarket catted downpipe or go catless.

No - midpipe is less of an issue for moving from map 1 to map 2 - you need to upgrade stock DP 1st. Plenty of folk running high boost tunes with standard exhaust intact but with DP upgraded.
