this little guy is made by Apexi & i found it on www.yr-advance.com :

& shown here on their N1 muffler...

 

What is it :-\

 

it is a cockpit adjustable flapper valve to control the "loudness" of the exhaust by restricting the flow.

 

i ty sir

 

in stead of res. buy a quieter exhaust.. go loud or go home... loud pipes save rice.. i mean lives

 

hell yeah.. my dad told me about his friend that had an old ac gremlin.. horrible looking little ****box. but a small block chevy engine with mad hp. and then would pull up to mustangs and they would look over and laugh.. he would pull a swithch or something and open the exhaust up and they would be like WTF .. light would change. mustangs would get owned and take the next right.. hell yeah i got to get one of those

 

i agree. here's the exhaust used on the Varis EVO i wouldn't mind having:

old style cutouts look in summit youll see them. but the biggest they come is 2.5

 

be alot easier to order if the website wasnt chinese. (no disrespect intended) cant understand.. anybody sell these here stateside?

 

You are thinking of electronic cut-outs. Those are valves that Y off of the main pipe in front of the cats to completely open up the exhaust and bypass the cats, resonators, and mufflers. Gives the car more power and a helluva mean sound.

 

hope this thread might help some of the Cali members.

that website is a shop that only does Mitsus. everyone should check them out. i used www.worldlingo.com to translate the website www.yr-advance.com from japanese to english.

i also want to see if anyone can get the Wako's coolant booster & AT/diff additive as well.

 

it's in japanese & see post #11.

 

They are good for noise (my friend had one on his S15) but they do noticably drop power even when fully open.

 

I used to use one of these but removed it after about 3 months. Just didn't quite like the idea.

Apexi have come up with something else with a similar effect:

It will rob you of some HP according to the local Apexi distributor - they dyno'd their car with/out it. IIRC it was something like 8 - 9 whp, but I'm not entirely sure but definitey under 10 whp.

 

Because our EVO's are made in China
