Default Exhaust idea

I was thinking about having a new Y pipe put on and after that instead of one muffler connecting to two exhaust pipe having 2 one for each pipe(thinking flowmaster 40 because I want it to sound better than my magnaflow 14' I currently have) Besides the sound would this be better than what I have now, would that help my low end power or hurt it since mflowmaster has some restriction yet it would still be practicly true dual.

That would not be a y pipe if I understand you correctly. If you go that route, have a H-pipe welded in connecting the two pipes after the collectors. Right around the tranny pan. This equalizes the exhaust flow and produces more power and a broader power curve.. Do not go with anything larger than 2-1/2" pipe unless you plan on forced induction.

Post pics and update the thread! Very curious how it turns out. I think a good H-pipe/true dual setup will make a big difference compared to the Y-pipe.

How about separate pipes from the convertors to a Magnaflow Tru-X muffler, then stock tailpipes?
