When i first got my jeep about a year and a half ago, the first thing i did was exhaust. I had it done at a local shop, i believe they put in a flowmaster 50 series or w/e. And coming out the back on the right side it Y'ed off into 2 3" stainless tips. (if that makes sense)
So fast forward to last friday, i had them redo my exhaust similar to the SRT style with Thermal R&D 5" dual wall slant cut tips. All they did was bend new pipe to come out the middle of the jeep and used some sort of Y to attatch the Tips.
I believe the pipe size is all 2.5" or 3" I think its 2.5"
And its not dual exhaust it goes 2-1-2 tips
So since i have had it back, around 1100 rpm my jeep makes really weird noise and maybe some vibration. Then it does it again around 3k rpm, Its almost like a sound right before you stall out.
If anyone has any idea what this is let me know, The only thing i can think of is the bigger tips dont provide enough back pressure?? I really have no idea? It does seem to be alot louder too, although this could be the different placement of it , but i do think its louder.
