What is the difference between

MAP Stainless Steel 38mm MVS O2 Eliminator Downpipe

and

A regular 02 dump

???


I mean stating the obvious u get rid of the internal wastegate, but NOISE wise, and performance WISE any different?

 

They'll both sound the same but the o2 elim dp has the performance advantage with lower weight, less chance of exhaust leaks, and less turbulence with the disadvantage being a more time consuming install.

 

MAP's downpipe is a full 3" most o2 dumps are not.
The noise level should be the same with both.
You may see a small power difference with the MAP o2 elim DP vs other o2 dumps.
