Had a little issue putting my exhaust together yesterday. My buddy suggested going to this exhaust shop in New Lennox, IL called Sassers Custom Exhaust for some help. Mike took care of the situation I had and was very helpful. We spoke a little bit and he does anything custom and he seems reasonable. We discussed possible solutions with the catless Y that comes with the Pacesetters and he said he could add Cats to the Y. I have no affiliation with the shop but just throwing some props out for this guy. It also seems like there are some people always looking for custom exhaust shops that are around. He is located somewhat close to Route 66 Raceway.
