if you remove it, it will be louder but could drone on the highway. If you do replace it, you want the pipe to be the same diam as the catback

 

thats what i meant....i bought this 3" catless dp...which is amazing..and then bought this stainless borla catback kit. the resonator section is pretty much identical to stock section. i installed it all and it sounds very "tuned", and good. but it is not quite as loud as i would like i mean.....so i want to know if i should remove the resonator section from borla and have a new 2.5" pipe bent from testpipe to muffler.....or get a 3" pipe bent from testpipe to muffler and adapt it to the muffler....or leave it alone...but i want it louder...

 

ok so i want it the same diameter as the catback? and what do ya mean drone on the highway? so it will be louder?

 

Drone will be a constant humming noise. If you can get 3" from the dp to the muffler, that would be fine, if you are removing a part in the middle of the catback, just replace with the same diam.

 

i will not be removing the section in the pipe, i will be replacing pipe from downpipe to muffler...so should i go same diam or 3"....

 

.....?

 

It's all the same BUT buy new bolts. They are stretch bolts & with the more of a grip with stronger rubbers it'll need a equal or better "backbone" holding on.

Then just do 3" but make it not perminate just incase it gets to loud or drones and you want to go back to the way it came. I personally would just wait like clipse said and give it like a month for the sound material to get some heat in it and get to the final dB level

 

i dont see how the 3" pipe would connect to the dp....it just has bolts at the end for the reducer..
