Has anybody removed the giant center muffler and replace it with straight pipe or a less restrictive muffler? Just wondering about any sound and performance changes.
No the centre silencer. The van has 2 after the dpf.
Unfortunately deleting both won't change the sound. It will give a tad more turbo whistly and a bit more meat to the sound but nothing audible.
On diesels the dpf steals all the noise.
I have a pp tuning twin exhaust with a small straight through packed silencer. No real change in sound. Just a tab more meat and turbo whistle.
