I am seriously thinking of getting this too, the extendo one that eliminates the u bend and has the cat/o2 sensor..heck, its only 230 bucks..that is cheaper than getting a replacement cat at some places.

I have a Jimmy C DP.

I would guess they are all about the same, so I wouldn't think you will see/hear/feel anything different between zzp and Jimmy C. It's pretty simple tube bending and welding with a high flow cat. The issues with the whistling and baffles has been fixed for years.

Personally I like either the offroad or the high flow cat models. These bolt up, eliminate the U Bend, and give you a 3" DP at a great price. It's the best value by far.

I would definitely go with a zzp or Jimmy C model that is stainless though. I have one of the last "coated" steel DPs and I wish that I had waited 2 more weeks and gotten a stainless one...but I got a great deal on mine, and it works so that's all that really matters.

You will feel a difference with a DP though.

I also have a custom one. I dont think that there is too much a difference in any of them anymore. There are a bunch of places that make them. Ohio Auto Worx, W-body, Jimmy-C, ZZP. im sure there is more

"After the cat, it flattens out into a section dubbed the infamous "U-Bend," which is a section of pipe crushed into a "U" shape by GM in order to fit a rear O2 sensor. This section has less volume than the same length of 2" pipe, and approaches the volume of a 1.75" pipe with the rear O2 sensor in place! Our bolt-in downpipes eliminate all of the aforementioned problems! Gains of over 15HP have been seen, along with a substantial drop in knock. Most users can drop a pulley size and/or eliminate 5-7 degrees of knock."




For a lousy 213.00 (that includes both front and rear gaskets AND a cat!) you can't go wrong, replaces U-Bend and is a direct bolt in. I will be ordering mine next week.

Here is a good picture of the dreaded U-bend
