Will these fit perfectly with magnaflow competition 3 inch exhaust?

lalo08

  • As long as the flanges line up with each other, this will fit with the Magnaflow Competition 3" cat-back exhaust.

do these work with my stock exaust?

lalo08

  • Hello! This Kooks Off-Road X-Pipe will work with stock exhaust however it is designed for people who are using the Kooks long tube headers. Unfortunately this is not designed for the stock manifolds or shorties.

with a little cutting and wielding can i make the bbk long tubes fit with the Kooks Off-Road X-Pipe 3"?

StreetKing

  • Hi, We do not recommend mix and matching brands when it comes to headers and mid-pipes, I suggest only using the Kooks Long Tube Headers 1-5/8 in. Item# 65526 with this X-Pipe for proper fitment. Here is link http://www.americanmuscle.com/kooks-longtube-headers-9604gt.html

ok, will the Kooks Off-Road X-Pipe 3" fit with the Mac Long Tubes Headers? I want a Monster sound!

StreetKing

  • This will not work with the Mac long tube headers as the Kooks X-pipe is specifically designed for use with the Mustangs equipped with Kooks long tube headers.

I have short tube headers, can I still install these pipes?

StreetKing

  • Unfortunately, this x-pipe is designed for long tube headers. It does not include the down pipes that will connect to the shorty headers.

if i got this x pipe and later decided to add the kooks cats to it would i have to buy the whole catted version or could i just get the kooks cats for my current kooks x pipe

jay

  • If you are looking to at cats later, all you would need to have done is have the cats welded into the Kooks Off-Road X-Pipe - 3 in (99-04 4.6L for Long Tube Headers). I would suggest having this done professionally.

    Kooks O/R-X Pipe

    Fits perfect with the Kooks LT Headers. Only issue I have seen is the clamps could be better. After a couple of bumps from bottoming out due to lousy roads, the pipe had to be re-adjusted from the clamps. Instead of the clamps, it would be better if it was a one piece welded x-pipe. But overall, still high quality.
