I have two exhausts systems I like to run. One is the Ti mufflers and one is Borla strait pipes. I go through phases where I like the car to be tame and streetable, but most the time it only leaves the garage for drag racing.

I went out the other day to try and swap my straits on for a drag race tonight. Love the noise, lighter weight, and they are what the car is Dyno tuned on. But of course, even after stacking wood on the jack, I just couldn't get the car high enough to get the Ti's out.

Now I know the simplest thing to do would be to run cutouts because id have both my systems at the push of a button. But.. I am a tight wad with money for that kind of thing, and I know only racers will understand this, but it is added weight.

Swapping exhausts is very quick and easy. I had a set of Bassani mufflers that had a two piece over axle pipe. Unfortunately I sold that kit, hence picking up the Ti's. But now I can't do the swap.

So the idea I'm tossing around is simply having the Ti pipes cut and having some kind of slip fit piece to connect them. This would make the swap easy again and save the price of the cutouts. I'm just not sure if having it cut and something customed up is going to cost near what the cutouts would cost, and it would obviously lower the resale value of the Ti system should I decide to sell it..

Sorry, that turned out a lot longer winded that I expected. Just looking for thoughts on the best and cheapest way to go about this. I don't want to have to take the car to a shop every time I feel like running my choice system.

 

I am going through this right now.

I decided to go the cut out route.

By the time you pay someone to cut and weld Ti you could have the cutouts installed. And, you won't have to crawl around on the ground to connect and disconnect whatever kind of custom connections need changing.

 

Well I figured out what I'm gonna do. I'm doing cut outs, but not electric. For 150 bucks my muffler shop is going to weld in the two Y pipes and I'm just going to manually cap and uncap them whenever I want. I'd rather just run straits to save weight, but there are times when I need the car quiet, so I'll just do it this way for now. Plus I can always add eclectic operation later if I want.

 

The electric part about the cutouts is the only thing I'm not particularly crazy about either.

How are you going to cap and uncap?

 

Cutouts come with plates to block off.

 

Yep, and since I jack the car up to swap wheels over whenever I'm going to need it streetable, it's very easy to cap them off at the same time. For the most part it's just going to be uncapped.

 

Exactly what I decided to do. And the same reasoning...I'm swapping wheels at the track, so while it's up in the air, just pull the caps off...best of all worlds...hopefully.

I did have it dyno'd with TI on and then unbolted and dropped out of the way. About 11 whp. I'll take that.

 

Another positive to doing it this way is no electronic parts that can fail. I went with stainless pipes that will last long and there shouldn't be any issues ever. Knock on wood. Can't wait to have the sound back. Pfadt cat-less LT headers off a built engine going straight out the dump pipes!

 

Something to consider if you're wanting a system that you can swap out is the GHL Bullets. They are a three piece over axle system, which would allow you to swap them out just like you did with your Bassani system.

 

That's awesome!

Mine is tuned for the strait pipes, so hopefully this puts me closer to where it should be when uncapped. I haven't noticed a difference in power, just a huge decrease in sound. I'm sure it will add a few ponies to run it uncapped since it's tuned that way. If in the area of 10, that would be great.

 

Ya ideally I would have got another system that's easy to swap. But I got this Ti system for $100! And installed! So there was no way I could pass that up. And now with simple dump tubes, it's gonna be easier than ever.

 

I have been running the DMH cutouts for a long time now. Only issue I have had was when one lost the electric motor right at the 4 year mark. I was not driving the car, so I am not sure if it was a driver error or a part error. I have about 6 years on my other DMH cutout with no problems. It was the best solution compared to changing exhaust systems. The Ti is quiet, but great performance. The cutouts offer an increase in performance and the LOUD factor.

 

Sorry, I looked at the QTP cutouts and I still don't see how you are capping and uncapping.

The electric version is a baffle, correct?

I am assuming you do not install the baffle at all if you go the manual cap and uncap route, correct?

So, exactly how are you capping the pipe? Do you have a pic of this?

 

Its just a Y with one side goin to Ti mufflers and the other going to the air. The cap is just a plate covering the open exhaust hole. You take the entire plate off it doesn't rotate like electric.

 

Right. But exactly how is the plate attached? screws?

Is it a flat plate or shaped like a coffee can?

 

The setup I'm working on installing has the manual cutouts welded into the exhaust pipes before they go over the rear diff with plates that are secured by 2 bolts per plate. My shop will create a turndown for each plate with a flange that lines up with the bolt holes and can be changed out with the cover plate when I want to open up the exhaust and with a turn down that will direct the exhaust flow away from the transverse spring.

At least that's my plan at the moment.

 

Im surprised you havent just looked it up, here's the basic idea:
