I am going back and forth on headers (not so much brand, just cats or no-cats). I cannot decide. I've been warned about drone and smell and also that cats are power robbers blah blah blah. Is anybody local running a SLP catback with LTs? Anybody that can take me on a ride or something? Catted or catless? I'm ready to pull the trigger, just need alittle bit more info before I do so. All the exhaust vids I've found are outside of the car, I want to hear inside the car and in person.
If it helps, my commute (when I actually drive it to work) is 11 miles round trip. 4 stop lights separate my house and my job. This car is my nice weather toy, although I've been driving it in the rain since the Saab has bald tires. If anybody local doesn't mind meeting up for a ride along, please let me know! Thanks!

I vote for catless. I haven't had an issue with mine, and I normally can't smell anything when commuting (yes, my olfactory senses function fine). Can't comment too much about drone as my dumps make any 'catless drone in the cabin' worse haha
I plan to get Gforce to tune it just because they are local. I ran open headers on my Z28 for like 5 years, with just turn downs at the rear axle and it was a beast. Just not sure about the GTO sound. Oh well, I can alway buy cats if I need to. Can't wait to get the LTs on!
Loudmouths sound like absolute garbage catless. Most terrible 2000ish rpm rasp I've ever heard, on any LS vehicle.
An 800whp turbo car lost 8whp with the install of high flow cats. You'd never notice the power difference. If you do go catless - your car is almost stock, you won't have the smell issues at idle that a cammed car would have.

Well I still have my stock system if I don't like the SLP with the catless setup. But def going catless to begin with just to save the extra coin. Figured I'd buy the woman something nice for Xmas too.
