headers (on jcwhitney)

[Pauls07]

hi, i've been doing some searching, and realized that xiogary doesn't produce the headers that he used to a couple years ago.. i've tried to find him on ebay but he has no items. so i came across these, what do you guys have to say?

Good find! Some of those pictures are Small Block Chevy but the vehicle is correct. Pretty common that parts sometimes differ from the advertized photo. Im gonna buy the Tight Tube Black. The Performance Black has a 1/4" flange ..... 3/8 flange is the way to go. Just my economy car .. dont need any shiny stuff.

I am curious as to how these work out for you guys, I have been wanting a set for quite some time now.

Does anyone have any numbers (HP) increases from these is it worth the 175 bucks ? I've almost finished rebuilding my 2005 aveo It was bored out 50 thousandths over, so I started thinking about the exhaust if I might need the extra flow.

Im thinking all these headers are just the "universal" type for chevy small blocks. Considering the exact same results came up for my 2010 with ecotec, when i know that there are no stateside retailers that sell headers for that engine

I was just looking closely at that site and Idk if you noticed but on all the pages of headers there is a red box on top of the product saying "this product does not fit your vehicle" sorry to burst your bubble...but here's a tip on what I used....I actually used a honda b-18 header....it fits almost perfectly....the #2 tube is off by very little other than that with some minor redrilling you'll have a head er that fits...

I paid $400 for xiaogary's header shipped from Malaysia... Gains were noticeabl , even after I went with 2-1/4 custom open exhaust from a local muffler Shop with a twister muffler. Bestgains wwould be attained if we could tune for them, but nobody local would do it.

I have a header off my B18A1 and last time I held it up to my current exhaust, it didn't look like it would fit.

So I just finished an online chat session with JC Whitney's sales rep, according to him the Hedman steel headers are an exact fit and maintain EGR functionality. That being said I will probably order a pair next pay check and let you guys know if they work.

And after rereading the description again (and finding out they aren't in stock) I will probably not be going this route. Found the following things that bothered me:
Primary Tube Wall Thickness: 18-gauge, Precision MIG-welded 16-gauge tubing ...... two different size tubings??
​Product Fit: Minor modifications required
