What exhaust section 1-2 would pair well with my setup?

Euro section 1 (catted), leave section 2 alone, get a quieter muffler.

Euro OEM sec 1 and OEM muffler. The oem design is meant to work as a rudimentary diffuser and helps prevent ballooning of your rear bumper at speed. Both functions which many of the aftermarket exhaust manufacturers seem to overlook or discard. Supersprint street if you insist on aftermarket though

Added an AR20 to my setup and I feel a loss of power in the mid range. Not sure if that's normal, but if euro cats flow equally well or only slightly worse to the resonators then that seems like the smarter option.

I would get a euro section one, and weld in two ar20’s to it.

How would that work? Cut off the cats? Seems it would be way cheaper to start with US sec 1.

I think he would just need to cut off the straight pipe section and weld in two ar20’s? I was fortunate to grab a early model cpi rtx section one with race cats for sale a few weeks ago and it’s the perfect setup for me. It’s gotten rid of 95% of the noxious fumes and 100% of the rasp
