Thread: Question for all those who have removed their muffler on a TD5

I printed out Ruslan's picture(thx Ruslan) and drove down to Midas today, the manager scratched his head and said that he and the boys never worked on a Defender before, they ummmed and scratched their heads and finaly came up with $165.00+, the plus was having to match Flanges as they were not sure what would fit, even mentioned laser cutting some one off pieces but that would require leaving the car there for two days to measure up and requote.............So that basically finished that exercise.......

Went up the road to Mr Muffler(in Frankston), beaten up old joint it was, but a cluey young bloke came out, looked at the printed out picture, slung himself under a wet car, and as he emerged out, he said......" I'll keep the existing flanges by cutting them off the Muffler segment and splice/weld them onto the new pipe ".....I looked at him, he looked at me....as easy as that........"How much I says' ???".........$65.00.........But it might be LOUD, the young bloke says......never done this on a Defender before!!!!!!!

Bugger I says, for $65.00, give it a go mate.......40min later I turn the ignition, young bloke has his eyes shut with anticipation.....sounds..... NORMAL............a little more deeper in the Low noise but otherwise sweet...........
I get in the car and take it for a run, ....noise level barely more noticable, but very pleasant note, not at all intrusive nor irritable, feels more stronger on Torque through 1st 2nd and 3rd. Turbo has a sweet new whistle, not agressive, it's just a little more pronounced......

I get home and put the car in for the final test, get the missus to go down to the shops...........
She comes back with, "I know you have done something to that monstrosity, but I'm not sure what, it feels stronger but I can't put my finger on it......"what did you do and how much did you blow on it this time".....

And that test sums it up, it's not too loud at all...............

Exactly the same the experience I had about a year ago.........was considering removing the muffler for a while and again it was a cluey young bloke in an near by exhaust shop (incidentally the same guys who make the Vortex system) who simply cut out a section and welded in a straight bit of pipe, oh and he also removed the resonator so my exhaust note now is a little more pronounced No chance of hiding the mod from my wife though......or the neighbours but still goes well and happy with it

Aye, Mick

I would personally leave the rear 'resonator' box on. It is straight-through and shouldn't affect flow but definitely takes the edge off the bark...which some people may consider to be a bad thing.

I replaced muffler on my 200tdi Disco with straight-through pipe and it definitely had an effect even though the standard muffler isn't particularly restrictive compared to say a Toyota. Wasn't going to bother with my S2Td5, but after reading this post, maybe I will.

Didn't know that new diesels had cats - if this is considered restrictive, might replace with a larger one...
