Default C5ZO6 Exhaust Question.

So I'm sure that I'm beating a dead horse right now...

I just purchased a 2002 Corvette ZO6. It is completely stock but I have a set of Kooks 1 7/8 headers on the way and I'm going to be running a catless kooks x pipe. After that I was contemplating keeping the factory catback since it is titanium and has a nice tone to it however it is 2.5" and going from 3" from the headers and x pipe to 2.5" at the catback is not going to be the best performance wise. I have full exhaust on my 2006 trailblazer ss with corsa catback and i like it but the corvette that i bought is for me and my father and he likes the traditional deep throaty muscle car sound but he doesn't want it to be super loud like straight pipes or slp loudmouth because i had borla straight pipes on my 2003 zo6 and he hated it. So i guess my question here is... Is there any 3" catbacks that will have the deep throaty muscle car sound I'm looking for but not be ridiculously loud and raspy? Im not afraid of a car that makes noise, i just want it to be a quality respectable sound and not something thats going to make me sound like a pissed off teenager...

Youtube videos are hard to tell exhaust sounds from so i not looking to be told to look on youtube.

Id like to stay away from the following:
all magnaflow products (I'm not a fan of magna flow)
all flowmaster products (no choke-master for me)
the borla straight pipe exhaust (too loud and raspy)
the slp loudmouth exhaust (too loud and raspy)
corsa exhausts that sound "exotic" because I'm looking for the deep throaty american muscle sound

outside of that I'm really open to anything. please let me know what you all think. Again I'm sorry if this is beating a dead horse and repetitive but i just want to know what everyones opinions are.

Ive heard good things about billy boat and borla. but again i want to hear what you all think. thanks for taking time to help me out!

If your motor is otherwise all stock your exhaust system from headers on might be too big for your engine. 1 3/4" would be better with 2 1/2" mid section. If you plan on bigger and better things, it'll be okay in the long run. My '03 Z has LG street system with Magnaflow cat back. Runs great and sounds good too.

There aren't many options when it comes to a 3" axle back. I have kooks 1 7/8" headers with the catted 3" x pipe, I was also looking for a nice quality 3" axle back so I went ahead and ordered the kooks 3" axle back to go with the rest of the exhaust. I'm still waiting on the axle back to get here though so I can't tell you how the sound is, but check out the kooks axle back, had decent size mufflers so it looks like it won't be too loud.

LG Big 3
Kooks
XS Power
Stainless Works

kooks also makes a true 3" connection. you may be able to exchange your 2.5" x pipe for the 3". i think im going to do this to mine. i know my stock TI exhaust is killing me power wise

I have kooks LT 1 7/8 with kooks X pipe with HF cats and stock Ti exhaust ... Its real quiet except when I get on the throttle and even then its a civilized but aggressive tone.

well I read many good things about the B&B bullets so I ordered the quad 4" round B&B bullet catback. I plan on doing my headers soon, I am waiting for my kooks to come in. But I think a bullet style exhaust will give me the tone I'm looking for (ghl or borla or b&b)

Hey my man. It did just a little when I first installed but LG sent the 4 tips out welded a bit off on the passenger side so I had my muffler guy bring two tips to the center and he welded a piece to hold them from moving(clamps). Not an ounce of drone since.. Very weird. I don't know if it's because of the piece welded to hold the two sides even or redoing the tips coming out of the muffler. But there is absolutely no drone.
