Straight pipe & engine

[rushh]

Hi everyone,

I have a Mercedes C250 2.2 Turbo Diesel I was wondering If I was to get a Straight Pipe done too it i.e. Removing Muffler and Silencer.

Will it harm the turbo or engine by doing this?

Would appreciate if anyone can help me out thanks.

Well, if you currently have a DPF and remove it, you'll need a (well-done) DPF-delete remap - as the loss of backpressure will affect turbo-spooling and other parameters.
Reducing backpressure will increase your performance, but a bad map may reduce engine/turbo longevity.
Also expect to your turbo to become audible through your tailpipe.
If you don't intend to keep the car, have some fun with a remap - but if the car's a long-term keep, you may want to look into the advisability of remapping at all.
Good luck.

My take on diesels is to refine them as much as possible by keeping them quiet.

Wouldn't a straight through pipe risk making the car sound like a dumpster?

Usually straight piping will help the turbo to spool faster.

Apart from making it sound like a tractor, it shouldn't really be detrimental to the engine. If you do de-DPF, make sure it's done properly...
