O/R H-Pipe Question.....

[Kurt04Mach1]

I read where some say you loss tq with it and some say you don't, does anyone have dyno number to check and see if they lost low end tq?

I bought a O/R H-pipe for my 04 Mach and I'm keeping the stock exhaust but after doing a search I a little unsure of my choice now.

Thanks
