I have the APSWRX-HOE/R2 3/2.5" with 4 inch tip for sale. It's been used for about 50,000 miles with no issues. You can see more details on this exhaust at the APS website.
This exhaust is great because it is not as loud(only 90dB) as the other APS exhausts and does the job for up to 525 HP. I parted out my car to sell it and move out to the east coast. This is one of the best fitting TBE out there(I've been through a few). I hope to sell it locally for $450 picked up. Please PM me if you're interested or if you want pics. Thanks.
