Exhaust and tunning

[j.fro]

The eBay headers are a great start. I had your "second thought" setup for a while. With no cats, you will definitely get a cel unless you also get the ecu tuned. This setup is really loud, over 98 dB at WOT. The SCCA hit me with a sound meter and threatened to ban me from AXevents if I didn't quiet it down. I welded in 100 cell cats and it did the trick. The Borla muffler is not the sturdiest piece. More than once I had to reweld the bracket that mounts to the trans. Oh, lots of drone in the 2500-3000 range. But it sounds like a cup car and everybody loves it, except for SCCA officials.
