Exhaust Cutout? Good idea?

[Velocifero]

so does the cut out go right after the cat? and if so does this mean you can buy a mid-pipe from somewhere and put the cut-out on right after it?

if that is possible to me that is similiar to buying a 3" exhaust for almost half the price

I have 3" exhaust and just recently put a cutout on it. I noticed a large difference so I would say that they aren't too similar.

no its not similar. i put my cutout right where my first cat goes. the point of a cut out is to get the air out asap! least resistance possible. even a 3" strait pipe will have more resistance. not too much mid you but it will. and of course any cats, resonator, muffler, etc will resist the air flow as well.

Anyone have an answer for this. What size cutout would you need for stock set up??

i think i am going to have the shop do this.. better then spending 1200 on an exhaust.. ha ha now do you think i should get teh S and jpipe aftermarket? or say forget it and just leave those stock? thats my next decision.. i want the exhaust cutout.. but THe S and J pipe.. what to do what to do

I'll be getting this soon. Iv'e wanted one for a while now.

Now, when I ran open dp before my stock motor blew, I noticed that my boost raised about 1-1 1/2 psi. Any of you experiencing this kind of spike with the cutout.

Stock setup is 2", but I replaced the midpipe with a 2" since I was at it... That way I can put the oem midpipe back for the winter so the salt and calcium won't damage the cutout.

0.5 psi in my case...

Thanks beaver, I dont believe they have a cutout for 2 1/4, guess i will see what midpipe in 2.5 costs. Thanks again for the help.

QTP has a 2" but In my opinion, I would go for a 2"

I have not checked the site, I am looking for bang for the buck. If i do a 2.5 cut out I also need a midpipe in 2.5 where as if i go with 2.25 then i can use the stock equipment and just buy the cut out. Also can .25 really make that much of a performance diff.

has anybody seen the cut out from ATP? I beleive it works off vacum it opens when you are on full throttle and stays closed if you are driving around town, until you crack it and it opens up.

[sbowers22]

I have a q-tech that I am trying to sell for $140 shipped and it is brand new in box never been used. It is a 3'' inch cutout.

 

[Myspeed12]

Raze R24 got them from www.edgeracing.com. But I have a 3 inch q-tech with the electronic flange for $140 if anyone is interested in getting one. The reason for getting rid of it is that I bought a 3 inch tb GHL and I am happy with that and the box just opened to see what it looked like then put away only had it for a couple of months. I just need to get rid of it to pay some bills with the money.

i know it defeats the purpose of having a cut-out but then what do you guys think there would be any benefits if you were to put it right after a catted mid-pipe. Would it be the same has having a j-pipe back exhaust on command with and electric cut-out?

 

[Myspeed12]

So for the MSP the 2.25 cutout from QTEC fit?

I'm actually thinking about one of these now...
