Exhaust Cutout Size?

Looking to add an exhaust cutout. I would like to confirm the exhaust size, my guess would be 2.5"(?) but prefer to get that validated before I place my order.

I'm presently looking at the NoWeed diverter. It's expensive but I've had QTP cutouts in previous vehicles and haven't been impressed. Anyone with experience with the NoWeed operated with their optional 3 button controller? Did you bolt it in or have it welded.

Didn't realize the question was that difficult

Anyway, I did some more searching this morning, but this time with dogid perseverance and confirmed that the standard exhaust is 2.5" as suspected. The primary question answered. Guess, going forward, I should do that prior to requesting help.

Sorry no help here, but I'm interested in your results as this is on the future to do list. Search the forum as this was a topic earlier this year or last year. Good luck!

I would say thatt 13 hour, overnight was not that long to wait for an answer. I know some have done the mod that you are looking to do but I also know there are many here that do not get on the sight during the week or only scan it and might miss your question. I am happy you were able to figure it out but please don't feel that you were ignored.

I think the ones I have are the QTP. Only had them for close to a year now. No problems so far.

Most likely you do, they are certainly the most popular brand. I had them on two different vehicles, both failed, over time from what I believe was improper use on my part. Being hard of hearing I'd apply power well after the unit had reached max open or closed position, burning out the motor. The NoWeeds (odd name) have an optional 3 button panel. With just the push of a button, you can fully open, half open or close the valve. A nice feature but they definitely charge for it. Again, I was at fault for the QTP failures, they are wildly used with success by a lot of people, just didn't for me.

Will do. Ordered the NoWeeds today, it'll be 2 or 3 weeks before they are installed. Been through some of the previous posts. One other member has the NoWeeds and someone also had their unit routed to bypass the muffler, connecting back up to the existing exhaust pipes. I'm hoping to do that as well, the objective was to divert most of the sound out to the back end, away from the cabin. I'll let you know how that works out.

I kinda like that idea of re-connecting back to the existing (Tail pipes).......not exhaust pipes.

My cut-outs when open kinda sound like any rattle trap with a blown muffler that needs to be replaced. Not the sound I was really after. I'm thinkin' that connecting back to the rear end of the muffler via the tail pipes might smooth out the sound and be what ya want.

P.S. While laying on a creeper under my SSR, I used the "remote" to my cut-outs and was able to determine that about 5-6 seconds was good for full open and/or full closed. Did not want to keep pushing the button as per your feedback and others I have seen, that just maybe causing a premature problem.

So they are NOT like running your power windows up/down...........where you can keepl leaning on the button, but it does not create a problem.

Hmmm I had true duals (2 cutoffs each) on both previous vehicles and never noticed a rattle, then again I'm almost deaf so that isn't anything to go by.

Yes your timing is about right. I saw on a previous post, the owner counting slowly to 7 to open/close. I can't remember what I used, but with my memory, anything more than 4 would be difficult. My wife says I could organize my own surprise party

Kind of the whole Idea of cut-outs is straight exhaust dumped out as close to the engine as possible and to be as loud as possible. The lowness of the SSR and where they dump out right under the seat area makes them very raspy and loud. That is why I don't have any. If you want the exhaust and noise to exit the end of the tail pipes there are many other options and applications to consider. Any way have fun with it.

That's what I'm looking for a selectable, loud/quiet option. I am unfamiliar with other options. While I'm now committed to the cutouts, I'd be curious as to what other options are available?
