Can you guys do a review on a 2in kooks off road

[@gamerscorem4staproductions775]

I have the kooks long tube catted headers on my '13 GT. It sounds really good but want more idle loudness. When I romp on it, it sounds perfect.

[@hassaan89]

Are you saying it's quiet(er) at idle and low rpm?

[@user-xc5es2ut7t]

Hey brother, whats the difference between the "Green Catted" kit and catted kit?

[@jinpengzuo9906]

I have this catted 1-7/8 on my 17 gt. I have a question, can you buy off-road (catless) part from kooks and replace the green cat? I want to go cat-less now regret got green cat, but we all know how difficulty to replace the header...

[@uchihaFBI]

do u know if we can get the catless part?

[@sicariusjack4201]

Can these headers go with the corsa connection pipes??

[@95cgjm]

Nobody can ever answer this question for me 😔

[@ryanpinon6527]

Can you run kooks headers with a Corsa extreme cat back?

[@uchihaFBI]

same question. please lmk if u got an answer

[@nooneimportant5880]

Yall ever find an answer?

[@ryandono5721]

Yes you can

[@gaivoron]

How’s is this a review? Most important is hp figures.

[@BurtReynolds.]

For real didn't even get to listen to the difference

[@dilroopkang8410]

can i run ford racing by borla cat back exhust with this?

[@jayyycee]

Did you ever find out ?

[@that10speed5oh]

yes u can i have borla atak , w kooks catted heads and they fit no problem just got done today

[@gt8674]

Do I need a tune after install?

[@habanero5.054]

Yes! You 100% need to tune it after

[@5.0gt2]

@@habanero5.054 Is it OK to use 2 inch headers with N/A 5.0 2018?

[@habanero5.054]

@@5.0gt2 I’m honestly not sure. The most common header I see used are 1 7/8th. 2 inch might be better for boosted applications but I’m not 100% sure on the 2 inch setup

[@gustavobonilla971]

Is there really that much of a difference in power between the catted and catless longtubes?

[@nikonhckr]

You'd never notice the difference. It's small enough that it could be considered acceptable variation on a dyno. Air intake temperatures would make a bigger difference than cat restrictions.

[@TheCdM1981]

nikonhckr or about 10hp. So when something only gives a full bolt on another 20-25. 10 can be a lot.especially looking at a tune install and pieces for about $2700 on average.

[@xGR1MxREAPERx]

The people saying 10hp from catless to cat are wrong. If you have turbos or a supercharger then maybe but a stock motor with a tune and headers and cai sees almost no gain going to catless. The cats that come on these are hiflow and barely do anything. On a dyno you see maybe 2-3 hp. Get catted and save yourself from the nasty smell and check engine lights. No tuner will delete rear o2 sensor signals anymore so not worth it

[@chrisw.7039]

​@@xGR1MxREAPERxI was wondering if catted headers would keep me from throwing a CEL. Wanted to know cause I didn't want to deal with the light coming on.

[@xGR1MxREAPERx]

@@chrisw.7039 my 19 mustang has kooks high flow catted and no dial harnesss or anything and I don’t have any check engine lights at all.

[@freedom6919741]

Is there really anything that makes the Coyote sound deep ? They all sound horrible with full exhaust and headers.

[@kevinduver]

The lowest I've seen is probably Borla S Type with an H pipe.

[@carlosg2677]

Only cuz of California...

[@habanero5.054]

Now no one can buy catless parts😂

[@austinspillane678]

How is this even a review lmao, no dyno results, no install, no sound clips. Sweet video AM👎🏻
