Shorty's to LT, 3" to 4"
Im currently upgrading my exhaust from SLP shortys to Hooker 2210 LT headers. Im also upgrading my Flowmaster force II cat back to a Mufflex 4" system. Ill also have a custom 3" Y pipe made, right now I was able to put down 375 rwhp 375 rwtq thru a 383 with Trick Flow heads, Miniram with a ZZ409 cam.
Im wondering how much more the exhaust upgrades will give me? Im thinking Ill be over the 400 rwhp mark, but not sure how much? Any thoughts? Thanks!

Ok then, let me rephrase the question. What kinda power gains should I expect going from shorty headers to the longtubes making around 375 rwhp?
