I think this is one of the best ways to do a cutout. It wasn't cheap but worth every penny. I have Pacesetter mids and a 3" high flow cat. I bought on Summit this 3" intermediate pipe http://store.summitracing.com/partde...5&autoview=skufor $48.38 and have it run to rear passenger seat where the cutout is. I notice the price went up to $82.39 so I am glad I got it when I did. The cut out was only $24.95 and I got the Jegs electric opener for $225.00. I paid the exhaust shop $60 cash for the install and it looks way better then I thought it would. The car sounds incredible and fully open it vibrates a little but 2/3 open or less its almost as loud but is real crisp and no vibration at all. For around $360 I did what I would call the best mod on my car. I ran the wiring harness through the drain plug in the bottom of the back seat foot area and ran it through the interior out the firewall to the battery.

 

with your FI app you probably get a good amount of power too.

These things are great. So much fun to fool around with.

I did a couple 0-60 runs open and closed and had better times everytime with it open so it appears to have helped me. My muffler is more of a restriction than most.

 

I can see gains on a restrictive muffler (Blowmaster). On mine, I swore mine felt faster with the cutout open according to the butt dyno. I think it was just a different experience due to the louder exhaust.

The real dyno said no gain when I was at 300RWHP. Now I am at 412RWHP and I have gains of 2-3RWHP with the cutout open. The Borla just flows this well.

 

When I had my SS dyno tuned, with the cutout open, I picked up 4 rwhp and 12 rwt.....................

 

I never added the electric portion, but I have been very happy with my manual cutout. Definitely added some much needed sound to the exhaust note.

 

I've had it on for a couple weeks and have played with the position as far as sound and vibration goes. 1/3 open it sounds like a very nice muffler and deep tone. 1/2 way open it sounds like a cutout but not too loud with a tiny vibration. 2/3 to all the way open its super loud and vibration is most obivious at low rpm's and cruising on the freeway. I have the loudest car around besides the 500+ hp racecars at the track. I keep it closed at the track till the race so i don't scare away the other cars.

 

mrmint69 question which shop you went too for your exhaust work? I got to do some work on mine...

 

Doc's muffler on Division 1 block south of Francis.

 

Thanks...
