Notice any cons from rear muffler delete?
I've already searched to no avail. I think I will be doing a rear muffler delete this weekend and was wondering if anyone that has done the same has experienced any major cons they had to rectify? Any noticeable loss of back pressure or torque? Is it the resonator delete that really has to do with loss of back pressure?
Just trying to get this done and make sure it's safe for the vehicle.
PS: Safe to not have straight pipe to replace them right away? TIA!

Wasn't looking to remove the resonator, but thanks anyway!
I had trouble finding someone on here and YouTube with JUST a rear muffler delete, NOTHING ELSE, still have the mid muffler and the resonator; so I'd like to emphasize a bit on the sound I hear (without a sound clip). The shop that cut them for me says it sounds like a "sports car" now. I have to say I agree. It's not loud or obnoxious at all. Just more sound basically. Sounds like a v6 sports car with a CAI, if that makes any sense. Thinking about removing the mid and leaving the resonator; just don't want it to be crazy loud. Going to try to find some sound clips.

Okay, so now I obviously want louder. Thinking of leaving the rears deleted, installing straight pipe, replacing the mid muffler with a hi perf muffler and leaving the resonator.
Any thoughts? (yes, I'm leaving the stock resonator)
We all know the mid muffler is smaller than the rears. Is there a beneficial reason as to why it is specifically smaller? Think there'd be back pressure/loss of power issues by me installing a bit larger (aftermarket) muffler there?
TIA!

Mufflers and resonators are to silence sound.
think of the origin of the word.... Muffler....To muffle ......Resonator ....Resonate....... To be filled with deep bass.
So, in other words removing and straight piping them will make your car sound like ass.
Back pressure isn't even in play here

Also, how is back pressure not in play? The shop that is doing the work for me specifically mentioned that I should keep the resonator so I don't alter the back pressure to a noticeable degree.

^you are correct, I did not read your original post.
your plan to replace it with a performance one is good.
the origin of the word is resonate. which means to fill with deep reverberating sound.
if you replace it with a straight pipe, you wont lose anything! you will gain LOTS of noise!

What back pressure? You are not creating any restrictions to cause back pressure. All you are doing is changing the rear mufflers to "high" performance mufflers; altering sound.
Not sure why you think you would lose torque as all you are doing is altering the sound of your stock exhaust.
You will be fine.

Thanks for the input, guys! Going to go through with it. :3

I posted it to help give you some direction - if you click on it, it gives you a breakdown of the "stages" of exhaust with some sound clip examples. I know what you were saying and trying to do, but having some base ideas of components also helps.

On a side note though, considering PCD > stock resonator > glasspack muffler (replacement of MID muffler) > straight pipe.
Still debating on the glasspack or whether or not to leave the OEM mid muffler. Don't want it obnoxiously loud.

that will be obnoxious most likely. my car just has the precats and rear mufflers, everything else is deleted underneath and its got a pretty loud but deep tone especially on cold start. the precats actually do a good deal of sound reduction, without them and just a glasspack and resonator i would think its going to be very loud

Mr. Detail
Get a long tube j-pipe (it deletes the 3rd cat), remove the mid-muffler and replace the resonator with a Magnaflow or Dynomax. You'll have a deeper idle, a nice growl when you get on it and very quiet at steady freeway speeds. And the J-pipe will give you more gains than anything cat-back will.

Right now I have stock precats > resonator > cherry bomb glasspack > straight pipe. Sounds almost exactly like I wanted to, I love it! I say almost because there's a bit of rasp every now and then when revving at low RPMs. But other than that, it's got a nice, subtle, deep idle. Really sounds good from 2k-3k RPM and anything above really. & of course quite when I'm just cruising, which is good for my 2 year old.
I'm DEFINITELY getting the j-pipe, just trying to space things out because I just bought wheels & tires. When I install the j-pipe, I'm thinking of installing two Magnaflow mufflers a client of mine is giving me for free!
EDIT: What?!? I can edit posts now!? Anyway; yeah, I agree, PCD would be too loud on this current set-up. & now that I've thought about it more, if I do go through with modding the pre-cats, it'd probably be HFPC (smell of PCD is a major con for me).

Resonator Delete
I just had the same convo with someone else, I removed the resonator and had a straight pipe replace it and it has the gurgle like a 350z and sounds way better too , I feel the car breaths better and feel lighter, it was cheap and I like it, lmk if you need a sound clip
