Thread: Exhaust on 300tdi

Well after reading lots and lots and lots of various sites and threads i think I may have come to a conclusion! Maybe if I had a 4.2L pootrol I'd go a 3" but on the defender with the outlet on the turbo/exhaust that is an extra .5" either side!!

My decision is leaning towards 2.5" or 2.75" from the turbo, with a hotdog in place of the centre muffler and a straight through Resonator on the rear maybe with a 3" tip.

What do you guys think

I would be going with either of those sizes, I've played around with a few different exhaust systems on 300Tdi's and can say you will most definitely want to be putting a resonator at the rear of the car, without one the drone does get very annoying on longer trips (even short ones to actually!). I would say leave the middle pipe section without any muffler and see how you like that, its not hard to get it off and put one on (or get one put on) if you think you need it. But from my experience I've found leaving the middle one out just gives a little more of a noticeable turbo whistle not an increase of droning noise!!
That's just what I reckon

Let me know what you decide

Hey Defendozer,

Im going 2.5 straight through with a single straight through resonator at the rear.
Can't wait to free top end revs up and get the temp down a bit
