hi

ive heard a few evo`s with external dumpvalve and they sound pretty good all i wanted to know was that can i put one in my stock evo 8 fq300 and how much would they be.also if anyone can tell me how to make it sound like this evo (http://www.youtube.com/watch?v=KItyWBpUgoE)
help would be really appreciated

thanks

 

if you are running the stock turbo you can get a jmfab/epm/qtp/shearer o2 dump...or you can get MAPerformance's external wastegated downpipe set up

 

and yes then it will sound like the car in the video LOL

 

dose it give you more power

 

Yes it does give you more power. That one in the video is a EPM o2 dump. I have the same one in my car. At first i hated it because i thought it would be less like a turbulent exhaust sound and more like a TON of air rushing out. I honestly wanted it off right away. Then i got used to it and i am in love with it. The reason is at normal driving, even semi-spirited its completley quiet. Then when you want it gets LOUD!!!

 

Yeah you can get it for the stock 8 turbo

 

whats the difference between dump and a cut out would a cut out be better

 

im eventually going to get both the cut out and i already have the epm dump tube. so pretty much its going to be loud at idle"cut out" and get really loud when i boost"dump tube".

 

cutout implies that a flange opens in the exhaust where the test pipe would be...thus shortening the length of your exhaust

o2 dump strictly dumps the excess wastegate exhaust and lets the exhaust flowing through the turbo flow through the exhaust as it usually would

both do the same thing...take away restrictions and decrease back pressure

 

You're in luck as these happen to be a part of our Black Friday sale Click the image below for more information on our O2 dump and use discount code bf20 during checkout to get an additional 20% off! Keep in mind this is today only!

 

Silly question, i know..but...

Would this part NEED a retune? What problems could persist without one?

 

I would recommend a retune as your afr's will be changed because of the increased flow.
