Ok here's the deal. I have some money set aside for headers, but the speed daddy headers everyone recommends are out of stock and when I called they said it would be weeks before they would be back in stock. It's getting cold out and I do not plan to install headers in the snow/cold ass weather. My car will occasionally get around 4* of knock retard and I'm looking to get rid of some of that so I've been looking at getting just a downpipe and get some headers come spring time. So my questions are:
-My car has stock headers,and also the stock u-bend. A downpipe will help my knock retard correct?
- what downpipe should I get ? http://shop.zzperformance.com/Store/...spx?itemID=249 I'm looking at the 3inch off road pipe with an o2 bung welded in.
- this is direct bolt in to my stock exhaust manifolds right?
Anywho, my car is a top swapped gt with a stock pulley. I don't plan to do too many other mods for awhile. I just want the setup I have to be safe. Will a downpipe suite my needs?
