Default simple stupid question

I have a TSP rumbler catback and I want to order a QTP electric cutout.

I know the HP gains aren't going to be much. I want it more for the sound. my question is what size cut out do I need to order? 3"?

its a tsp rumbler and I'm assuming I will mount it in the I pipe there. Should be 3". what is stock size? I searched and I think the stock size pipe is 2.75" right? all QTP offers is 2.5 and 3". should I just order the 3" and put it in the portion of the rumbler?



Never mind. I just looked under the car. The 3" pipe is not long enough to mount a cutout before the muffler. So It will have to go in the stock part of the I pipe. So what size exactly is that? 2.75"?

do you want this for daily driving? if so your probally better off getting a catback. especially if your reason is for sound.

Well budd you cana get 3", but I used to have the Rumbler and I wanted to add a E-Cutout before the bullit, but it couldnt be done the torq arm was in the way and would hang wayy to low. I wanted it before the bullit or else it wouldnt be much of a diffrence. So i sold the cutout.

The HP gains are going to be zero and the sound "gains" are going to be minimal. Check the stickies for more cutout info including installation pics.
