My truck was has been making a rattling noise for a while now and apparently it turned out to be a bad muffler. So i got it replaced today at a close by muffler shop along with the 2 cat converters and added a new tail pipe.. However, after replacing them, the thought came to mind: Does it matter what cat converter and muffler goes on the Land Rover? The ones put in were MagnaFlow converters and a FlowMaster muffler..Is that okay for this truck and does it effect the performance? I really didnt notice any difference in the driving, other than the rattling noise gone away.

 

I have the Magnaflow Catback exhaust muffler on mine. To my knowledge any muffler should work on the Discovery. The resonator is not necessary and only deadens engine sound further. I have heard other folks on the forum put on the Magnaflow converters with no problems. Others can correct me, but I think the back pressure from the engine is set at the headers. I think you should be fine. How do you like the sound of the Magnaflow? I think its one of the most affordable performance exhausts out there.

 

As long as you don't live in California, shouldn't matter what cats you use.
Will you gain any power, maybe a horse or two but it will sound awsume

 

Thanks for the responses. I honestly dont hear a difference though. I dont know if its just me, but all i hear is the sound of the engine. I was expecting a better sounding exhaust system but it sound the same. I know they are MagaFlows because i saw him install them and the Flowmaster muffler
