i doubt you'll lose any. having an open exhaust will do nothing but help performance. i don't know where scionlife got this idea that having back pressure after the turbo is beneficial in any way.

however. if you are gonna run an open dp. i would get it tuned the way you will be driving it.

 

well i had the ptuning on and one day i just wanted to see what open dp would be like and i loved it lol. nothing like being loud and obnoxious with the sound of a spooling turbo.. especially when u let off the gas and it slowly stops spooling.. some random guy was like "what is that a dump truck" haha i started laughing so hard.

 

i drove with open dp for a few months. cops never seemed to care
car was much faster
the way it sounded didnt matter to me
function over form

 

yeah we installed a dezod kit here and the dp was hitting the trans and we couldnt get the s pipe on.. so when we did the test runs we did it with straight dp and it was hella loud!!! everyone in the neighborhood could hear it! the spool sounded so sick though!!! in hawaii you will get pulled over fast..

 

lucky, i drove round open dp for a few weeks didnt get stopped but back in the n/a days w/ the exhaust i had i would get pulled over, i thought it was weird being in miami and all. so i just cut the tints have a rather quiet no cat exhaust on my turbo now and i love it...+ the open dump is awsome i love the unexpecting driver who just so happens to have his window down ahead of me lol dump then bov in their faces ....the ultimate satisfaction

 

yea man thats whats best about the open dp is that crazy turbo whistle.

 

^^ yeppppp gotta love it

 

no sorry i dont, i dont really have anyway to strap a cam to my hood besides duct tape

ps ive been meaning to talk to ya, pm me

You can run a dump exhaust by just running the down pipe and thats it ?

 

pretty much unless you wana spend the extra money on a straight pipe, but its a waste...just make sure ur DP is not like pointing at ur oil pan ,

 

Since I won't get your tube til after the turbo goes on, I'll take before and after shots with the camera mounted in the front of the car, for maximum spoolage.

 

LOL yeah that wouldnt be a good combination haaha

 

cool

 

sweet

 

Hey what do you guys think of running a electric cutout , bolted right to the downpipehttp://www.xcceleration.com/images/X...utout/dmh1.jpg

 

yup that good to have, silent when you need too.. badass when you race..

 

hey ace had another question on that electric cutout , when its closed where does all the pressure go to ?

 

it goes to you regular pipe towards the back of the car, when it opens, its gonna bypass your exhaust directly to atmosphere like running a very short exhaust and reduce back pressure..

 

I took my exhaust off and left it at the s-pipe(sounds sick). I know there is a 02 sensor on the spipe. I want to run the car from the downpipe. Where would i put the 02 sensor from the spipe at ?
