looking for some cheap xmas ideas here and thinking about a cut and clamp or splice in x pipe. i know i wont see any noticeable hp gains, maybe a few, but how much does this piece change the exhaust note of a car? my exhaust set up right now is just mid mounted m80's (pypes mm). rest is all stock. if i'll see a noticeable increase in sound i'd be all for this. thanks and let me know!
