well i have been wanting to do something to my exhaust for a while not and was thing about the high flow cat and removing the resonator? howdo you guys think think this will sound?

if u still plan to retain your stock mufflers it will sound decent. i have a hi-flo magno-flo cat and a 2.5" catback to the stock mufflers. removing the resonator will cause the exhaust tone to be a little raspier but, again, if u plan on keeping your stock mufflers it wont sound too bad.
I wish I had kept my stock catback. I did have my resonator removed on my stock catback and it sounded ok for a V6...the quieter the better.IMO
I gutted my cat, and kept the stock resonator, and changed the mufflers to some dual chamber flow masters.
A stock resonator will keep the rasp down, while giving the car some great sounding attitude through out the whole RPM range. Not just at idle.

Really? I've not heard a good sounding V6 yet. But then again, my first car with headers and full exhaust was a 72 Chevelle 350. I suppose what sounds good is relative.
At Branson I most liked the sound of Reptiles car at idle and Trannymans Cutlass.
Can the stock resonator be put on a 2.5" catback w/o causing restriction? My GMPP resonator took a dump. Meineke put another resonator in it's place, which I thought made little difference in sound. However the restriction was so great no matter the pulley, I was getting 6* of knock. Remove the resonator and removed the knock. Thanks to Dave for finding this.
Its hard to get a good sounding V6 I agree.
The stock down pipe, stock cat and if equipped with a u-bend is the most restrictive parts of stock exhaust. Next closest thing is where the pipe splits at the back to go to the mufflers, its not a smooth transition, like a free flowing "Y" its more of a "T" shape.
Reptiles commented on my cars exhaust, and has been in it with the cat back dropped at the track. I dont remember if it was a good comment or a bad.
At idle...I have a pretty good rumble, and a "ting" here and there which I think has a lot to do with the cat being gutted. Hard to explain...you hear it, you can tell what I'm talking about. I can start my car for you at Branson this year if you like.
A picture of my exhaust:
Before:
After being "refreshed" for this year:
Old installed picture when it was redone after my car was rebuilt after the accident.
I reused the mufflers, though the right one was bent, we made it work again. It only had like 1K miles on it before I was creamed, wouldn't you try to reuse it too. LOL
After the resonator its 3" pipe, but because nobody in town has a nice bender...its done the old fashioned way, crushed and formed. So some of the bends can get narrow is why we did 3". The first time we did the exhaust, before the accident, we did 2.5" and when we made the bends, it was down the same size as a stock pipe. We learned, and made changes.

I do believe you can go through Hogan Performance. They have the piping you might be seeking.
Mandrel Bends
And if those don't work out for ya? I am sure you could probably email or call him and tell him what you are seeking and he could probably fab you a pair? You would have to ask him on that one directly on that one though.
Just a thought.
I had my resonator removed I think it sounds alot better, mine doesn't make any rasp noise that is talked about. I was worries when I did mine that it would sound like crap and it doesn't least to me.
thanks for all the replys one other question..i was looking at a few different downpipes and high flow cats. i was looking at a zzp one and random tec one. i also talked to someone at an exhaust shop and he said something about the high flow cat may trip the ses light..anyone have this problem.
there have been a few incidents with older designed dp's tripping the SES light, but there are at least 3 fixes for this:
1. get a spark plug anti-foul bushing (right thread count/pitch is vital here), screw that into the o2 bung, annd put the o2 in the bushing.
2. leave the o2 as is, and use a powertuner/similar to delete the code from the PCM
3. get an o2 simulator, and block off the pipe's o2 bung (or if you want to be stealthy, hide the o2 sim, and leave the stock sensor in place, route wire as to not show that it's not connected.-- for visual inspection)
