I've read the thread on gutting the cat. Just curious about those wh have made this mod, what your general impressions are. My only exhaust mod thus far is cutting the tailpipe flush and drilling two 1.25 holes. Anyone dynoed with this mod? I don't have plans for modding changing the ECU. Sounds as if top end might improve a tad. But seriously I have know idea.
HBFL -Don't know about gutting the cat, but out of curiosity since my fine pre-owned beauty came with a full Yoshimura exhaust (no cat) I found a graph on the web put out by Yosh indicating a gradual increase in hp compared to stock beginning about 5k with up to about 6 hp by redline. Personally I spend a very small percent of my time at those rpms and I feel like the improved sound (tone, noise, etc.) is MY biggest fun from the mod, and your mods may have already gained you that. I would be hesitant to gut the cat in view of the possibility that Big Brother might take an interest down the road. Call me paranoid, because I am.
