Header & Test Pipe CAT Eclipse 420A

[bih55]

did anyone here get this for their 420A motor, there is a hole about an inch or bigger on my stock piping just before the cat. so I wanted to replace the pipe with this cheap ebay header. since I dont have the inspections in my state i wanted to remove the cat also, what do you guys think. right now because of the hole in the pipe from a start it pulls kind of slow, but in the upper rpms it really pulls harder

I'd say go for it. My friend had a 420a with about the same problem as you and he had the same setup, basically. It made a world of difference in his response time. Not, persay, going to make your car hella-fast, but you will notice a bit of a difference... especially if you have a hole knocked in your exhaust.
