Thread: Exhaust on 300tdi

I just got the center muffler replaced - $60 - left the stock resonater as it is straight through, did that 13yr ago and its been good. Noticed a slight improvement in takeoff and on steep hills, but that soon fades into the background Main reason got it done was to stop sticks hanging up on it, works! Why would you need to replace whole system? mines a 96 model and its still like new! Unnecessary cost me thinkith its not like u need to run the 1/4 12 tenths quicker!

agree, at first i just removed the centre muffler............but when the tpo come along they said it was easier to replace the lot

Ahh, oki well you got it at a good price any way so no grief in that But I dont think I would bother for a "road: going machine again unless it was destroyed by some mishap or as part of other upgrades \

Thanks Rick!! I am even more in two minds than I was before after reading those!
I do like Defender200tdi FAO Rick thread, makes me wana go to 3"

UGU80 - i have seen the TF pipes, Id like to get the whole system done though

Landie333 - Id love to learn to weld but due to comitments dont have the time at the moment to

Im hearing mixed responses from lots of people, Some swear by 3" on the 300tdi, some think 2.5" is the go as well :P

Is there really that much in half an inch??

Thanks for the reples guys!

About 40% more cross sectional area, sounds like a reasonable improvement to me.
