Most people will say the smooth bellows is a waste of $45. I don't have one so I can't say. But I don't think you'll see one on my car. A lid is worth the money, definitely. I just put a SLP lid on my car and I am very pleased with it. There is a sotp difference.

 

Go for the lid. Bellows are not worth 45 bucks. Stock ones seem to fit the best anyways. I dident notice any gain with the lid,but it looks a hell of a lot cooler.

 

The bellow is not going to give you any gains whatsoever and for the lid gains, please get ahold of the latest GMHTP. They tested seven different lids and listed gains for each and every one of them.

I just installed a Direct-Flo a few weeks ago. Up top is where I notice the difference and the exhaust note is a little louder and smoother. Definitely worth the money.
