im still waiting on mine ;-( I also ordered from maryland speed ( I think u might have ordered 1 day ahead of me)... Great people to deal with

 

Ok, all i can say is wow!!! Put em on last night, got it retuned today. Wheatley and I were both very impressed at how it picked up. Glad i went 1 7/8, should compliment a blower no problem!!

 

I didn't go kooks (mine are pacesetter)
but power increase is noticeable
and I do get that "hollow" sound your referring too, at least I think we're on the same page haha, I know its not a leak and don't mind it at all

 

Mine sounds the same way..have had acouple people say my engine sounds wierd or if im running with no oil lol

 

Question for you guys . . What spark plug wires are you running with the Kooks Headers? I am going to change mine and just wanna know which model will not get in the way or Rub the header on the driver side
Thanks in Advance

 

msd 8.5mm super conducter they run about 70-100 bucks

 

When running aftermarket headers is it needed to change spark plug wires or something?

 

perfect thank you !!

 

I run the summit wires, about $60 for the 8.5mm ones

 

Looks like kooks changed there y pipe merge.
