long tubes with the stock mufflers were awesome.

Y you’re spot on! Deep but quiet! Gotta drive it a bit more but not impressed so far with the sound.

yup those are the ones and it does not have the valves after checking so I guess the sound is what it is. It’s WAY quieter than stock which is surprising and yes the motors are on the new mufflers.

Just installed the Kooks axle back and didn’t realize until now that you cannot select exhaust modes. It is way too Quiet now! Does anyone have any suggestions or have experience with these below? I want sound and also be able to select driving modes. I suppose worse case stock mufflers go back...

basically said the stock 350 tune is ideal and aftermarket ones are minimal or unsafe. I’ve been running the palm beach 93 tune on mine and runs great.

I came across them online looking briefly but wasn’t sure if it was $79 and then another x amount to have to have it programmed. Is it as easy as ordering?

Anyone have to have one replaced? Have a 17 and looking for the best place to get a replacement. Do I need to go to A Ford dealer to have it programmed as well? thanks

Bumping as winter is coming

I had greens on my gt500, 4+ years no codes. I can’t tune out the monitors but maybe pull a log and a tune update is what is needed. thanka s

you been having good luck not throwing codes? I splurged for the greens but keep throwing a 4030 code.

Thanks for everyone’s input! Much better now!

cool will have to check that one out. The kooks extension is I think 8” and is super stretched. Tryna find a longer option

I was getting an oil change and my tech told me I should order an o2 extender soon on the front drivers side as the one I had was so stretched tight that it would start to corrode. Couldn’t find much for extenders but I found something around these NTK 27063. I guess these work on the 350s and...

just was asking if anyone uses an impact gun to make life easy over tightening via wrench but had a feeling air tools are a bad idea on CF wheels.

Hand tight only And no impact guns?

Ohhh those are sweet too.

Awesome, thanks! I had thought that but then somebody mentioned to me the rears now might have a play with AFR so it made me wonder.

gunna give them a go
