I'm re-doing my exhaust due to a couple landscaping adventures. I will be doing a 2" all the way back and use baffles for restriction Pranav. Maybe we can collaborate.

" Racing makes crack addiction look like a mild craving for something salty"
Last year I ran on a 54mm restrictor on a brand new motor, 297/260.
After a full season, this winter I reduced my 2.25" pipes to 1.875" for about 18", and put in thicker gear lube, ran 304/261 on a 57mm.
I'll take it.
Yes on stock y pipe, my "restrictor" pipes are simply what connect the manifolds to the y pipe in place of the cats.
Downstream of the y pipe is a 3" pipe and dynomax straight muffler.
I need to pull up.my old dyno to compare the curves.
Comparing my charts it did not nose down any further up top; same peak HP at the same RPM. I just gained more lower range torque and the it looks like the peak torque number is a few hundred RPM earlier.
Same HP at the same peak RPM, just more torque and earlier/lower in the range.
Remember, it wasn't JUST the pipes, I took out some intake restrictor and also did run thicker gear lube this time for more protection.
