We opened up our exhaust to 2.5", and dropped in a K&N air filter to help keep the exhaust temps cooler. The noise is not that noticeable. Next, the pyrometer. I thought someone posted a pod that monitors your water, trans, boost, and exhaust temp. I can't seem to find the thread. It looks pretty awesome. I'll keep looking for it. Boise Muffler charged $100 for the install and I supplied the magnaflow 10416 muffler on Amazon for $68. K&N was $97 on Amazon part number E-4810.
