y-pipe and custom b-pipe installed...pics
This weekend I installed my cattman y-pipe and cattman 22" resonator. Brian was a pleasure to deal with.

catless y-pipe...
cattman vs. stock...
I had the resonator installed at a local muffler shop with 2.5" piping.
stock b-pipe...
b-pipe after cattman resonator and 2.5" piping to the split...
The car feels great and still sounds stock with the exception of the intake.

I ordered the parts through Brian at Cattman Performance. He gives a 5% discount to .org members and is a great guy to deal with.
I installed the y-pipe myself and the piping and resonator install ran me $60. I've taken previous cars to the shop before so they gave me a good deal.

I totally disagree.. with that statement that drone is caused by the mufflers vs resonator.
I have the nismo exhuast and i removed the nismo resonator due to excessive volume under load and highway drone at lower rpms. I swapped it out with the stock tank resonator and any and all drone has been removed by the stock resonator.

Yep, I swapped out the mufflers on my wifes 02 Mustang GT and the drone is pretty bad at certain RPMs. It sounds wicked outside but it's always a trade off. It was the only change we made to it. I mean that resonator is there for a reason but your biggest culprit, IMO is going to be the mufflers.

It's difficult to say exactly how much noise was eliminated when I took my nismo catback off and went back to the stock system but it was a lot. I do know that the drone was too much for me when I had it on.
After I added the cattman resonator and 2.5" piping to my stock mufflers, I did not notice any change in the sound of the exhaust system from the original stock setup. Maybe the y-pipe has something to do with it.
In any case, does anyone know where most of the power is lost? Both stock pieces look pretty restrictive.

This pretty much sums it up.

As far as power loss goes, I point to the Y-pipe and the rear section "Y", and piping size. That stock B-pipe with the crimp is really not that restrictive even though it looks bad.
Real world experience: before going to the 1/4mi track on night, I gutted my stock y-pipe cat and replaced the B-pipe with straight pipe, it made ZERO difference in my track times. Slight difference in tone but other than that, it was a waste of my time and money, but hey, I gave it a try.
Your Cattman Y-pipe and the 2.5 piping back to the mufflers is probably making the difference you feel. Too bad you did get a dyno with that change. That would have been telling.
I still think your system came out clean though and as long as you are happy with it, that's what matters.

The fact is we are both right... Of course if you swap out the Nismo exhuast tips which are not restrictive and free flowing, for stock tips which are you will expereince a drop off in volume just as you would in swapping the resonator. They are all "mufflers" its the type of muffler and specific set up. I've had three different resonators on my set up and it is now quiet as can be with the stock res.. Except for the fact I've now added a Y-pipe.

compare that to this

Now tell me which is louder..

First let me say this was a nice setup. Install looks clean.
Now to weight in on the mufflers vs resonator. Before i upgraded my exhaust system i had straight up stock system. then i got a pair of magnaflow 1405's. they had a nice little growl to them but i wanted to get it sounding a little louder so what i did was installed a magnaflow resonator (thanks Gollum, LoL) with is a lot smaller than the stock resonator. At first i was excited about the louder growl, but around 2k-2.5kRPM the drone is numbing on the inside unless i step on the gas a little harder and get past 3krpm.
So now i'm thinking of putting back on my stock resonator because my girl cant take the drone when we're driving in normal traffic and to tell the truth it's giving me a headace also...
but now i have another prob. when i swapped out my stock resonator at the shop i forgot there, went back the next day and the guy threw it out . A brand new one is $200+. So anyone out there wanna get rid of their stock resonator plzzzz lemme know. thanks.

[QUOTE=VigilanteMax;6876404]have you done this? Also change your mufflers (if you havent already) and see the difference.
I sure did
You are right Ill. The Magnaflow did kill some of drone but not enough. The cruise missile is back on.
So there you go kids. I went from a straight pipe to a small resonator and back to stock.

[QUOTE=rich2342;6876601]This clip is with the Magnaflow mufflers/resonator:
http://video.google.com/videoplay?do...15790029&hl=en
Since I tacked on the stock resonator back on, about 85% of that fabulous growl is gone. All you hear now is the Fujita CAI and a little bit of the muffler. That resonator is huge for a reason. My car sounds like this now. Very similar even with the Magnaflows (Not my vid).

Believe me, I toiled with the idea in my head for sometime because this would be the third time that I had to go through this process. I had to go with comfort because my body told me to and so did my GF and friends. Nobody wanted to ride with me
#34
Yeah, I folded to the pressure too when I removed the nismo resonator for stock. But is just sounded so sweet going through the gears. oh, well.
Mine sounds much better since the y-pipe install which gives a very modest growl very Z'ish.
#35
So you have stock mufflers with the stock resonator?
#36
Nope, y-pipe, stock res. connected to nismo exhaust. clip below. no drone when im driving just a nice z'ish hum
