I have been trying to knock off as much weight as feasibly possible while maximizing power. So far my sc400 is down to 3100lb with a couple gallons of gas. I realized my exhaust layout was not optimized for my goals. I have 2.5" rush extractors feeding dual 2.25" mandrel pipes and a magnaflow x pipe and dual magnaflow mufflers.
I figure by running a "single" exhaust thats fed by a well engineered merge collector "Y" pipe, I can elimninate 1 muffler and 6 feet of exhaust piping. This would mean another 15lb of weight savings.
Is it possible to exploit some extra HP by running this setup?:
-Rush 2.5" header collectors feeding...
-2.5" Burns stainless "Y" into a 3" main pipe. (3" too small/big?)
-Mandrel pipe (straight as possible) to a single 3" ID Canister with 4" out?
Right now the system is very mellow, and downright silent at idle and low rpm. I dont mind it getting a bit louder but I want absolute uninterrupted flow and maximum hp. I plan to tune this motor N/A with adaptronic once I get a loom from Neil. Here are a few pics of the current setup (phone pics, sorry):
