Hopefully they'll be cool since the y pipe w/ cats is more expensive 
I'm not so much worried about WOT as I am about the sound level inside while cruising @ 65MPH doing 1800-1900 rpm.
Thanks for input guys, keep it coming

Well I have Mac's, custom ory and Gmmg. Let me tell you its LOUD!!!!!!!!!!!!!
Highway cruiseing has rasp and drone. I went for a 50 mile cruise with the wife and daughter. Needless to say I installed a Moroso bullet that next week. No more rasp. No more Drone. I can drive the car at over 2,000 in the city without getting a ticket. Anybody that has this combo will Know exactly what Im talking about. The bullet worked great. I can actually have a conversation in the car while cruieing, at WOT its loud but nice> At the race track my instructor and myself could talk but had to yell during WOT shift/driving. Track officals voted me the Best Sounding Car over the weekend. Not to loud, not to quite, Had a muffled NASCAR sound that they loved. Onlookers could tell where I was anywhere on the race track

I went from the Corsa to the GMMG, but only because I went through 2 mufflers, and was fed up with waiting for new ones, and having them welded on again. I really liked the sound. It woke up with headers and a cam.. It's just not worth the money in my opinion. The only parts of the system even worth anything are the tips.
