Are they easy to install? I plan on doing it myself.

 

Easy to install, I did put the back end on ramps. You have to take off 4 brackets( some say you can do it with just taking off 2 but easier just to take off the other 2 for me)

 

I just talked to a guy at car show with 2010 GT ... he just installed the Flowmaster Classics ... square body not round. Said there is definitely a drone between 1800-2200 RPM ... He started up the car and revved it at the show ... they sound really good!

 

Thanks for the info guys. Since it is my daily driver I think I might go with the regular American Thunders. They might get a little sound boost with a 91 octane tune.

 

I have the Classic 40's on my 06 GT.

Here's a vid w/ stock cats.

Flowmaster 40s FTMFW! Someday I will have them once again.

 

I'll sell em to ya for $200.

 

Um...using annotations to cover up a LP number doesn't really work.

 

I know. I just don't really care to take them down.
