bigger exhaust Hey everyone, when I had my resonator taking off last year I have notice they replaced it with smaller piping, looks like 2.25inch, so I'm wondering if I should change it to 3inch and leave the 2.5inch at the y pipe.

i have 3 inch from the cat no res manual cutout, and 2.5 y pipe.. if i could do it again, id save the money on the bigger piping and just use it on an electric 2.5 cutout right after the cat.. but thats just me, i love loudness

How does it sound to you Will?? If it sound good then just leave it and get a cutout. I plan on leaving ALL the exhaust stock and just putting in a cutout when I get my headers installed. I already have my cutout, just waiting to get them installed and tuned at the same time.

I don't plan on putting a cutout on.

Had my car up on a hoist today. Had my res removed by a muffler shop when I first got it and it is indeed a smaller diameter (2.25) painted with rust inhibitor...?? lol. I am getting a 3 inch custom DP + 3 inch high flow Cat then sizing it back just before the res delete. So 3 -> 2.25 -> 2.5 = lol
Price:
High Flow Cat $100
Res Del $175 ( Got screwed )
DP with install $300
Total = $575

I'm gonna get this done in june....3" and leaving the magnaflow Y and mufflers the way it is....Wonder if it will sound louder, because now its 3" to 2.25" to 2.5"
Think about blowing into a straw with the middle pinched. The gas has to be pushed out the entire length of the exhaust so the whole thing should be open.
you still wanna keep some back pressure. I honestly don't know how bad that would make it having the 2.25 in there, but since the gas vapors get smaller as they cool down may not notice a difference

i think if does get louder it wont be a hugely noticeable difference.
True. You do not want that 2.25 on there. single 3" or dual 2.5" minimum. The sound difference with be negligible, then again so will the power but every little bit helps.
