Thread: 130 Defender Exhaust Question!

I have done similar, removed the centre muffler with straight through pipe, left the rear resonator in place but havnt removed the cat... YET..
Mine is also still just as quiet, i figured removing the cat would make the difference, maybe you should try unbolting it before the resonator you put in see how it sounds with out the 2 resonators so you have a real straight through exhaust then!

i had no meaningful increase in dB fitting a 3" exhaust to a MY10 130. cat removed, new centre muffler, no resonator. That said the reason for a new exhaust was the old one had rusted and the centre muffler was cactus so it might have been louder than stock.

You'd be a more sensitive man than I if you can detect an improvement in performance over the stock system.

I have a 130 with a hs 2.8 tgv. This is basically a stroked 300 tdi.
I run a 3 inch exhaust with no mufflers or resonators just straight pipe and I think ive heard the exhaust note twice. Its very quiet.
The only time I hear it is when I drive close to a wall or through a tunnel. I have to be up it though.
Cheers
