I figured this was the case just couldn't believe I had three shops tell me it blew my mind. Like they wouldn't make it if it didn't work.
Since you do builds and I honestly know little too nothing just what these "shops" tell me maybe you could give me a little input. So I had the resonators deleted and they went with stock piping back to the Y then about a foot of 3" piping in to a 3" in/out bullet then dumped before the axle. The new Y pipe(that hasn't been installed) is 2.5 in 3 out. Should I have the shop make the pipe where the resonators were2.5 all the way to the Y?Look at the Cajun Ypipe, I use that merge all day in my builds. Cajun Bpipes | shreveport, LA 71129
I eventually will go headers I'm thinking just getting 2.5 now. Is there any difference in sound between 2.25-3 and 2.5-3?Maybe some low end torque but your not gonna gain till you Uprev and add headers. 2.25" to 3" like the JBA catback ypipe is your best bet with the stock manifolds.
