injen dual right now

 

The JIC Rear section with the XYZ resonated section does not help much with interior noise. It'll still be loud. But now it doesnt freakin buzz my brains when I accelerate in the 2500-3000 rpm range. It is also quieter when just cruising. I can have a conversation now.

I decided to buy the resonated XYZ y pipe because it made a big enough difference to make my exhaust quieter.

 

This just came in from MRC.

Its the plot of all the rest of the runs from the plumpzz test. Both pre and post.
