Gutted stock DPs

Randomaccess335 · 01-14-2013, 05:50 PM

So I decided to gut my stock dp's, i was surprised it only took me about 30mins. I'm going to put them back on for a final dealer visit........ But I think I'm going to leave them after, I know they won't flow as well. But I can't imagine hp loss is that much compared to aftermarket.
I searched and didn't find any comparisons.
Anyone have a Dyno comparison ?

If you're running stock turbo w/aggressive tune you'll be ok.
The stock DP's are great because they are double layer = less noise.

Aftermarket DP flow better tho due to size, less bends
