Exhaust Suggestions / Assistance

I' pretty happy with the dynomax ultra flo mufflers. Straight through design, the 3" flowing 1300 cfm each.

318? I recommend a jegs 2 1/2 mandrel bent kit w/o mufflers and buy a pair of ultra flo mufflers. The sound is great, deep powerful with the right tone amd volume to keep a convo in the car.

I run a 410 sb w/hedman 1 5/8 headers, full 3" jegs pipe kit, ultra flo. While you'd see a drop in rpm of about 400 between the 3" and 2 1/2 due to way less restriction/back pressure...you'd also lose a lil torque under the cam or the first couple thousand rpms leaving the line with that 318. You don't really wanna give any up, I would think with that small a cid.
