Full cat-back system

I've been looking around for full cat-back exhaust systens. Downpipes and mufflers. Borla has peeked my interest and was wondering if anyone on here has it on their coupes and and comments.

Thanks.

I actually have. I've seen that the AR has catted and that they are a sponsor on here. Maybe I'm just a newb when it comes to searching these forums...oh well...

yeah get the AR catted for XI and a nice downpipe back (so you remove the middle cats) .
Best is catless dps though for max performance and less backpressure. Keep your stock midcats and get a nice catback. There are many options .

Thank you for the recommendation. I'm looking into catted because I know I won't want it so loud and deal with any emission issues. I guess I still need to figure out this whole exhaust thing more. I didnt know I could remove mids and run catted and down nor the stock mids and aftermarket cat. Is there anywhere you can point me to read what the +/- are?

Thanks again!

Downpipes and an exhaust would be a turbo back exhaust...

I'd go with ARD or AP downpipes coupled with AFE/AA catback exhaust...

AFE has a catback for cheap. It's like $900 something on **********'s website.

AR DP's + AE Exhaust (you can get both with cats). Will set you back around $2000 if you buy new, but the sound is intoxicating.

The AR downpipes and the AFE cat-back exhaust is the setup that I would recommend for you!

thank for everyone's input!!! I was wondering what the difference is for catted DPs and catted exhaust? Is there any drone with the AT? My 70mile round trip commute caused the AT purchase vs MT =[ not as fun I know...
My goal is a actually something I heard a while back in a mall parking garage where a turbo 911 was just leaving the structure and was sounding all sorts of sexy and ready to set off car alarms. I have no idea what or how he did it but I knew I loved what I heard. (just side bit, I'm sure no one has a clue what I'm talking about)
