Update: Added back a resonator

For anyone considering the Magnaflow (and maybe other after market exhaust upgrades) system without a resonator, you might want to add a resonator after all. While I love the sound of the Magnaflow on my truck, the drone between 1800-2200 RPMs started to drive me crazy. My wife and kids also hated it.

To resolve the drone, I had a local muffler shop splice in a resonator. The exhaust tone is still nice, and now the drone is gone and my family doesn't hate the Rover anymore.

Will report back on any issues/success/failure/etc.

Hey Chris, quick question for you. did you purchase the Magnaflow 93689 Stainless Direct Fit Catalytic Converter 99-04 LR Discovery V8? I just installed a cat back exhaust system on my D2 and want to replace the Y pipe/cats with a Magnaflow thats more free flowing. I live in Virginia so no CA emissions worries here. Thanks!

Looking at the options on AB and RN I am unsure what will fit right other than the Genuine part that is mega expensive. I live in WA state so no CA emissions worries here.

Thanks for the help.

Hi guy's. Are there any 4 inch exhaust systems out there that alow you to fit you standard catted y pipe on for MOT time? If not is it really worth replacing the the down pipes power wise for the hassle of changing the full exhaust every year? Thanks
