Bigger exhaust for 300D turbo

[Philabuster]

Hi All,

I have read about increasing the power output of the 617 engine (manual trans, intake, intercooler--Ridge). However, I have not found any threads about improving the exhaust. Almost all the *big* diesel mods start with increasing the exhaust diameter for better flow.

I recently put 3" mandrel bent exhaust from the turbo to tailpipe on my Diesel Scout with the Nissan SD33T (3.3 liter) engine. It made a huge increase in bottom-end and mid-range torque. Throttle response is also much improved. Granted, I was going from 2" pipe to 3", but I made no other modifications outside of a K&N air filter.

Anybody tried this on a Benz?
