So I recently installed the full exhaust system by ebay. Headers/test pipe/muffler, and its WAY TO LOUD, I'm not quite sure what the best route to take is to quiet this thing down. I've been poking around the interwebz and found exhaust inserts see below. Seems kinda ghetto but the reviews seem good and its a low impact install that doesn't add much weight. Does anyone have any experience with these sort of things or have a better alternative? I always seem to modify cars until I ruin them, its so easy to get carried away.
