I've been looking through the exhaust board for the past few months, and don't see Hemdan Hedders brought up that much. (Talking about the $200 pair, not the air ones.) Are they as restrictive as the Edelbrocks? Easy to install? The only installation issue I can think of is the O2 sensor. If anybody has these headers, please show some feedback and opinions! I have a gutted cat and flowmaster 80 muffler too so I'm hoping the headers will really open the exhaust to work to its full potential. Thanks guys.

 

ttt... no opinions on these??

 

I got the Hedman headers that dont have A.I.R. and they were around 200$. They arent all that good ive had them for about 3 months and replaced the gaskets on them 3 times. I dont know what edelbrocks are like but they make reducers that have a hole in them made for O2's
