hey guys.. ok Im a little confused as to how big my exhaust system should be..
so far im leaning towards D&D headers but 2-1/8" primaries... but for the rest of the exhaust, Im not sure if I should go with a 3" or 3.5" system, exiting before the rear axle.
also, im looking into magnaflows and maybe this dynatech cone turndown to further reduce the decibles without causing backpressure.
545 w/ about 10.5:1 comp, P-51 heads out of box, hydraulic roller cam with about .643/.635" valve lift and 253/248 @ .50 duration with a 112 LSA, 1050 dominator and edelbrock victor manifold.. also using 3.73 gear with a 28" tall tire.... the project hasnt even begun yet, but i want to plan everything out before i start... i think at the end of the project, the '85 T-bird that we're building should weight around 3300 pounds... possibly, and also making at least 680 [email protected]
6000 with about 700 ib-ft peak @ 4500
also i want to know if i should go with an H- or X-pipe... or none if not recommended... but i want something that is going to be optimal for performance but also quiet enough not to bother the neighbors... besides the fact that the exhaust pulses will probably blow up my house .... yea...
but anyways, besides knowing that most of my questions should be answered upon my own opinion, id like to hear what others may think might be the way to go ;-)
