Pros-Decent sound, good price, looks good, noticed a bit more hp, definately more kick in lower gears during acceleration. Cons- Doesn't come with passenger side hangars to hang muffler and pipes so expect to go out and buy some at auto zone or just order some from cjponyparts. Sound isn't awesome but for a little of $300 can't beat it. nothing h-pipes and new headers can't fix anyways. Would I reccomend- If my friend was on a small budget and won't mind buying seperate parts just to install it then sure.
