3 in or 2.5 in exhaust? Please Help!
Im about to purchase texas speed 1 3/4 longtubes and 3 inch offroad y pipe, my question is: Should I run 3 inch tailpipes or 2.5? I have a magnaflow si/do muffler exiting right before the rear tire, I want what will be best for performance. Thanks. Also, mods in sig.

FWIW, I just went from dual 3" to factory muffler with single 3" outlet - to a magnaflow 2x2 muffler with dual 3" tailpipes and it made a big difference on power output above 4k rpms. This is on a 5.3 based H/C stroker engine.

Okay, from my experience, won't 3 inch tails take away a little torque? Correct me if Im wrong.. I was wondering if it would be a major power difference or not.. Just to clarify, The system will be a full 3 inch system, to a single in dual out 14 inch magnaflow, im trying to decide on 3 inch tails to make a full 3 inch system or 2.5 inch tails, once again, each pipe is only going to be about 14-18 inches at most as it exits in front of rear tire. My tips are 3 1/2x10 I think. Somewhere in there.
