Well.. maybe not a COMPLETE replacement for an exhaust but its pretty damn cool...

This is posted about once every 2-4 weeks haha...

Can't say search though, because something like this is almost impossible to query.

It's cool for some, though I wasn't a fan of the design. It doesn't follow the natural path of the exhaust gases.

 

is it really... i have seen cut outs... not ones activated by boost.

I heard that a lot of the electronic ones malfunction and the manual ones are just annoying... Having one mechanically controlled by boost seems interesting.

I talked to my shop and they said it is actually a worthless mod with very little power to be made... but it makes your car SOUND reallly fast..

 

If you have a turbo, and you want to make it sound faster, get an open dump tube for your wastegate.

 

or just make it go wooooo

...and in partial boost situations it sounds like a long huge fart when the valve flutters.

 

haha open dump FTW my car sounds like a train!

 

check out my dyno sheets in the dyno day in hawaii thread. i made 20-30 whp by opening my exhaust cutout and about 5-10 mor wtq. i run stock exhaust with the second cat replaced with a y-pipe with the cutout installed so it follows the natural flow of exhaust gases rather than a 90 degree opening like the atpturbo one in the link.

 

At least you have the Y adapter. that helps a lot.
