I saw these headers on eBay, they have an extra flex pipe between the front down pipe and the j-pipe, I wonder if this design would be good against resonance. Any ideas?

 

haha I was just looking at these 2 sec ago on ebay. but dont know the answer to your question

 

From what I remember the reason for the multiple flex pipes was the fact that the construction was of such piss poor quality that they were needed to get them to fit.

I also remember someone posting about one of the flex pipes coming apart.

 

^ agree. Not to mention i dont like the angle the other pipe dumps into the main pipe

 

Gotcha, thanks guys. I tried searching but I couldn't find anything about them.

 

It comes in too straight from the rear headers and needs to have more bend in it.
