I have been looking all over for Xerd headers and can't seem to find them anywhere. All of the dealers say that they are out of stock, and that they don't know when they will be getting more. My question is...should I go with a Toyomoto header or a Pro-1 header instead? I am not sure about different gains or anything, I just want the one with the best performance (but I don't want to wait months on it). Any help would be appreciated. Thanks.

 

Well i am not too good with preformance stuff but i know that more people have Toyomoto header and i think i will be getting that header eventually. You can read about it at www.toyomoto.com but i dont know if that will help you. personally i never heard of Pro-1 header...sorry!

 

Thanks for the reply. From what I can tell Toyomoto and Pro-1 are basically the same header. I looked through some old posts and that is what people were saying. The Toyo ones are cheaper than any of the others, but I heard that Xerd gives the most gains. We will have to see...

 

Pro-1 and Toyomoto are the same.
I have the Pro-1 headder on my IS, good stuff
You eliminate 2 cat converters so prepare for louder exhaust!
