118D Exhaust

Post by jonners » Wed Jan 10, 2018 9:57 pm

Hi

Last year I had the standard Back Box on the Exhaust system on my 118D replaced, for a replacement by Ulter (it is a straight through Back Box whatever that means). However recently it's been playing on my mind, should I have the middle silencer removed? Will this affect the Engine behaviour in any manner? How much louder will the Car be? Plus will I need my existing remap adjusting?

At no point do I plan on removing the CAT/DPF as it just appears too risky under all the legislations.

Thanks.

I've had the mid box removed for a straight pipe, along with my Ulter straight through back box, there is absolutely no change to the sound whatsoever. It sounds exactly the same as it did by having a Ulter back box and mid silencer in place.

Maybe I am trying to justify the £50 spent, but there feels to be a slight improvement in throttle response and pickup in acceleration...

Meh I just dunno....

Is your car remapped or stock?

Mid silencer + Ulter Back Box
Straight through (no mid silencer) + Ulter Back Box

Sounds exactly the same volume wise. Between these two configurations. As above.

This brand new aluminised mild-steel performance exhaust rear silencer has a pair of polished stainless-steel TWIN ROUND (70mm Diameter) tailpipes. The 'STRAIGHT THRO' silencer provides a modest power improvement, along with a deeper tone compared to the standard exhaust, however it's not too loud!

Did you ever record before and after videos?
Can you also record how it sounds now please? I'm also wondering whether to do the mid silencer delete.
