Well, I finally took the giant leap and did it. I converted to a duel exhaust system on my 2011 GMC Terrain SLE-2. From the CAT back I had: Hemi super turbo made by Dynomax, 22" universal glass pack resignator down the center, 2 chrome turn down tips. I only did the resignator because it was a bit to loud. It has a great sound and does not sound like a fart in a can. I live in southern CA and Warner's Mufflers did the deed. They did a great job.

I always find it odd to see an I4 with duel exhaust..

Any throttle response change? or just cosmetic.

Yes, there is more response in the throttle. Not a terrific amount, but it is noticeable.

Most Subbies, and the 4 cyl Altima has duals. I like the look.

Did you notice this in addition to the K&N intake? What was the K&N like by itself?

Cool...I really like the looks of what you did. I think the only thing I would try differently is to emulate the V6 exhaust and try to route the tails out through the bumper.

When I had just the K&N on it, all the "noise" was up front. What I mean by noise is: the air getting sucked into the intake. My Terrain had a very good increase when I installed the K&N. Once the duel exhaust went on all the "noise" was evenly placed front to back and it was a good sound.

I didn't want everyone to think I have a V6 by going out the bumper. I like this look and wanted it to look different. There was even talk about running the duel exhaust out the center fascia once it was trimmed. I said no to the idea because maybe I would want to put a hitch mount on one day, and I didn't want it to look like a Cooper.
