EXTRACTOR QUESTIONS

[samlicastro94]

Hey Guy's,

Been looking at getting a set of extractors but am left with a few questions during my researching. Am installing a large cam shortly so think I might have to upgrade my extractors. I currently have a set of VY2 HSV 'extractor' header's and a twin 2 1/2" exhaust.

Does anyone know how the stainless empire/ultrex 4-1 1 3/4" extractors & cat delete's are?
They're ridiculously cheap almost too cheap however I've seen some good reviews on them surprisingly.… Are they decent extractors or a worthwhile replacement over the VY2 HSV extractors? What is the fitment like?

Thanks ​

They are better than the HSV when you are looking for top end, nothing in it down low though. The bigger the cam, the better exhaust flow you need, personally, I recommend and fit 1 7/8" primary 4-1's, I use Hurricanes, they are tuned length and have a decent merge into the collector.
