Does anyone here in the forum have the Kahn Exhaust retrofitted? If so, what are your thoughts? I’m close to pulling the trigger, but I haven’t seen any real world reviews/thoughts outside of a few dated posts here in the forum.

Thanks and much appreciated!

 

Doesn’t it void your Warranty if it is installed on a P400? That’s what I know.

 

This is not true. No aftermarket product inherently voids your vehicle's warranty in the US. Obviously if you install an aftermarket exhaust and that exhaust fails Land Rover won't cover it. However, if you install an aftermarket exhaust and your sunroof stops working Land Rover has no right to void your warranty. I'm being lazy and can't recall it's name but there's Federal legislation around this that was passed years ago.​​​​​​​

the kahn exhaust is a just a muffler delete with some new tips and the rear cover. It looks great but really over priced

you have a p400?

 

yup, P400 (2020 110 X)

 

i would suggest either Quicksilver or FI Exhaust.

both are valvetronic. you can control the volume level by opening and closing the valves. Only two systems currently that have valves

 

Has anyone installed an after market exhaust on the V8? I've seen videos and read about the Milltek, but was wondering about the offerings from Fi Exhaust and Khan exhaust systems for the V8. Milltek unit seems to drone more than I want, based on reports and video's.

 

i have a v8 with miltek with resonators. the “drone”with the resonators is very minimal. i added sound deadening during my audio upgrade which muted 99% of drone.

both FI and Quicksilver uses their own valves and manual control. they don’t automatically open even at higher rpms.

i had issues with my FI system on my highly modified Bmw X5M. The rare time i had to valet the car i was surprised with an extreme increase in exhaust tone.

the valet was rolling around town and probably redlining. So much back pressure with the valves closed it actually blew off one of the connector pipes.

so when i was deciding on system for the Defender i wanted something that would function as OEM.

But the valves actually stay closed majority of the time on the defender unless in Dynamic or high revs and then closes immediately.

I had the first Miltek system in US and at the time only quicksilver was an the only other option.

if i would do it again today i would go with FI. Their exhaust note is much different than anything out there

 

Have you tried any type of chip tuner on your V8? If so can you share which and the results?
