summit-Racing magnaflow Cat- 60-90 bucks Flanges from RRE-20 Weld it up and pop her in place. I believe mine was 94009A from magnaflow its 16" long, then i welded the flanges myself. I have an entire 3" MR system and the fit was tight but hey you can pass emissions!
Plus my MR resonator i bought for 70bucks was smacking my driveshaft at times WTF With the cat it, it pulled away from the driveshaft a inch or two

The summit/catco cat is excellent. And it maintains 3" outside diameter to the chamber. This means that when you decide just to use your car off road , then you can gut it and slip a 3" inside diameter pipe through. You'll then have a test pipe that will fool your friends and family that check on your efforts to help rid global warming.

my other option is has the flange off the DP and have the exhaust shop weld up everything.who makes a 3" slip fit DP for a 1g fwd?
