Hey guys I just recently go a straight pipe welded on my tl after the catalytic all the way to the back and I loss all low end torque. Feels like I loss all low end completely. I want to know What happen? And what can I do to fix it. I'm planing on going back to the muffler shop and put back on my 2 stock resonators and go straight pipe after that will that bring back my low end? Please let me know before I do it. Before more money is put down the drain. Sorry if I sound like such a noob in advance.
