Default Cat-back vs. Cold air filter intake

i was wondering what anyone thought would be a better upgrade.

right now i just have a stock exhaust system and a bigger intake filter.

what would be better for gain, sound, and gas mileage.

If you already have a bigger intake, then go for a free flow exhaust system to compliment the improvement in incoming air.

Go with the exhaust. I have a Borla dual exhaust cat back system on my GT. Not too noisey and will give you a few more HP. I also have a K & N filter as well.

I went with a Borla system and if you ever want baffles, you have to order them directly from Borla, and they're permanent. I believe Bassani has removeable baffles. I wish I'd waited and spent the extra couple bucks on a Bassani system.

Plus, I did the cat-back and I wish I'd done a simple axel-back. The stock muffler has a single piece of mandrel-bent (correct term, yes?) steel that runs from the cat back around the spare-tire. The borla system comes in 3 pieces and mine, although tight, has a bit of moisture/ condensate that runs out from the middle connection - especially when the humidity has been high in TX and the nights start to cool down.

Also, if you ever want the Borla baffles (called "venturies" - and I don't know why) Borla wants proof that you bought one of their systems from an "authorized" reseller. I bought through Ebay about 4 years ago when the dealerships were trying to unload all these PT Cruiser accessories online since folks weren't buying them in the showroom or from the "stealerships" as after-market upgrades.

Just my $0.02.

Some thoughts on exhaust...
A dual is just for added looks - a free-flow single exhaust is every bit as good as duals - and a single is cheaper.
I like BTG - it is really flow-thru.
Be sure to go to a PT meet or PT Club and listen to an exhaust before you buy - music to one person is noise to another.
