Dude it acts the same way. All the cut outs are for is it to have a normal exhaust while cruising but when at the track or messing around you open the cut outs so that it sounds like it has open headers.

 

yea bro that and it will help you get that s*** out quicker.+1HP.LOL

 

I'd never put a hole in my exhaust...wth, just take the flipping cat out and a decent muffler if you want noise. I think the worst thing you can have is ricey exhaust...that sounds like rice to me.

Sorry if I ruined the thread lol.

 

lol that makes me feel a lot better knowing you thought there was no difference in the way yours sounded at first, thanks... i mainly wanted to make sure i could keep it stock sounding when i wanted to (to avoid tickets and pass inspection)... i'll make sure they install it before the cat
