This is the thing on the exhaust where you pull a lever and it closes off the rest of the exhaust and lets the exhaust gas go out an open pipe before the cat.

Can anyone explain how to do this mod or does anyone have a write-up for it?

Thanks in advance.

*edit* Also, if anyone can correct me and tell me what the real name of that system is called, that would be great.

 

They are called Cutouts.

There are electronic ones.

The ricer in me always wanted to hook one up to VTEC

 

Oh cool thanks for telling me what they're called.

Does anyone make a kit for this or is it a DIY?

 

my boy had this lever in his teg that he pulled up and it opened it up from the header. He just welded a y pipe on. It got stuck open and it was so loud.

He took it out. waiste of time

 

It's not really worth it unless you go to the track, in which case you can open it for a little extra power...

Not too sure if it would be worth it on our I4s though...

 

I gained 10whp I guess it was a bad mod......... http://www.quicktimeperformance.com, they suck, but it gives you a idea look at qtecs. Manual are better then electronic

 

thanks for the link.

anyone else got anything?
