Collector size? - 02/13/09 07:57 PM

What collector would be better for my engine 3 1/2 or 4inch.
My engine is a low deck 499 with indy heads, roller cam that made 761hp and 695tq with two inch headers and 4inch collectros.
I have new headers 2 1/8.
What do you think would be best 4 or 3 1/2?
The guy that did my headers said he tought that the 3 1/2 would be better what do you guys think any real experinces?

I would use a 4" merge collector with a 3.25" choke.
