anybody ever try this approach to an exhaust system? i was thinking about going this way instead of the full megan tbe. i thought it might be better bc i can be quiet when i want to so i dont get tickets from those damn cops, but when a race comes around, hit that swicth and bam!...what do you guys think?

 

There are a bunch of threads on this.... search is your friend...

I have no idea what a cut out exhaust is??

Edit: never mind

 

thanx i was trying to search for a thread on it but couldnt find one. So basically what do you need for this setup? a down pipe and a test pipe/cat?

 

You can chop up a down pipe and put a cut out on the DP or you can replace your cat with a cutout.

If I was going to put one I would put it in the DP and keep the sotck cat and catback. That way the closed noise is almost stock and the most gain from the opening being close to the turbo. But I have NEVER seen any dyno graphs to support gains.

anyone have a dynograph to support a gain?

 

Yes, my car is filthy... There are gains similar to driving with a full tbe, and the sound is undescribable. At 7k it sounds insane. Be warned you will have to clean it frequently unless you want to hear a slight leak while closed. I might actually be selling my setup here pretty soon... Pm me if interested.

can anyone prove significant gains close to one of a ull tbe with a cutout system?

 

search my name.. ive done dyno runs with this w/ a quicktimeperformance e-cutout..
i made 30+whp diff compared to stocker

 

I asked some friends about this.. Turns out my buddy with the SRT-4 has this done. Sounds mean, but i'd stick with a low grumble town personaly. And if there are gains, i can't emagine it's much more than one or two hp over a Buschur 3" TBE? On top of that, if you do this, you'll more than likely be keeping the stock exhaust set up after that cut off thing which will still keep you 20 lbs heavier over a Buschur as well. Not worth it IMO.
