True dual vs Y pipe exhaust
Anyone ever done any back to back tests of a typical 3" Y pipe and catback setup on a 98-02 fbody versus a 3" true dual to the bumper (kooks, speed engineering or TSP)? Just curious how much of a restriction my Y pipe and magnaflow catback is. I've got an 02 formula with a 383, PRC 225s with 11:1 compression, BTR stage 3 NA cam, ported fast 102/NW 102 and ftp lid, 1 7/8" headers, TSP catless Y pipe and magnaflow catback. Made 440 through unlocked converter (4l60e and yank PT4000). I've wanted to change up the exhaust for a while but if there isn't much to gain with a true dual or 4" mufflex style, I'd prefer the quieter magnaflow catback.

Not exactly what you're asking about but in the ball park.
1) My 91 RS w/LS1 383 Stroker made 445whp through 3 inch Y pipe to SLP Dual/Dual cat back.
2) With the electric cut outs open off of rhe headers bypassing the Y pipe & catback but otherwise exactly the same, the car made 465 whp.
Hope that helps.

I had the TSP Y-pipe on my 427 and switched to the SE true dual out to the rear, and it made 30hp more when i got it back on the dyno.
