It does have a raspy sound when you get on it and let off quick or rev it real high not under load but it's a v6 I've come to the conclusion that there is nothing I can do about it.
When I found out my muffs were rusted out I thought I'd do some research around the web. From what I read the resonator, the longer the better, helps reduce drone from the exhaust if you have no cat.

I don't have a cat (or a cat-back for that matter), and I figured for the right price I should just do a res while I'm hacking up a couple exhausts because drone is bleh, and these cars you really do need mufflers. So, I found a cheap solution: buy brand new resonator the right width from a member here for a good price, bought a complete '07 exhaust off of Craigslist with 40k on it for $35, sell cat off of that. Total investment around $35.

And I just loath that raspy sound when under acceleration then backing off, anythign to avoid/keep that to a minimum I told myself.

Personally, unless your pushing a metric-ton of power the 2.5" exhaust seems to be just fine. (from what I've read) And unless it's turbo'd and/or cammed then spending anything extra on exhaust on a GP just seemed pointless to me, like spending 1k to try and sound like a V8 as some people do. The only essential thing seems to be getting rid of the restrictive U-bend on the 6th gens. I'd rather spend the money on power mods than exhaust, if I was trying to spend money on this old thing, lol.

Just my $0.02, from what I've heard(literally, lol)/read. I'm still a noobie though, so pardon me if I got anything mixed up.
