Borla or the (nearly)identical to the obx exhaust you can get on eBay for $300. I bought a magnaflow and it's loud but I like it. I bought it from a guy that is now running the obx. He said if the stock exhaust was a 1 and the magnaflow was a 10 then the obx would be a 4 or 5. For $300 versus $800 for a borla it'd definitely be worth trying. If you don't like it return it. I personally love my magnaflow.
