Just finished first 500miles on new Magnaflow catback system and am extremely happy with the performance increases and the sound.
If anyone is interested in deals for a SS catback system try :

they are beating all other prices for now

 

Just wondering if you got the SI/SO or SI/DO

 

I got the magna flow installed si do ss for 460.00 with 22" x 4" polished ss rolled steel tips looks awesome and sounds great.

 

I stayed with the SI/SO because in the summer I am running 22" and the spare still fits underneath but I have to push it over to the driver side for clearance and did not want to get into clearance problems
