I did a lot of exhaust changing to finally come up with something I was pretty satisfied with.
The first thing I did was remove the stock main muffler and replace it with a Boral equivalent sized one. - This netted about a 5% change in sound - slightly raspy and a tad louder (was very dissaspointed!)
I then hacked the lunchbox and mandrel bent some tubing and re-attatched the stock tip - this made the exhaust slightly throatier again, but still not a whole lot of sound gain.
I then went ORP and it was somewhat ricey, and quite loud. I decided I wanted to stay legal and be slightly less obnoxious and bought the RT HF cat. This end combination is quite nice. It is just slightly louder than what the borla/lunchbox hack sounded like. I still wish it was a bit louder but id rather be slightly more stealth while having some fun in the car!
