What do you mean "where the second cat is"...are you talking about removing the second cat and placing this in there, or somehow putting it before the second cat?

The reason why I ask is because the stock cat-back exhaust isn't restrictive enough to where this would make a huge difference over just replacing the stock second cat with a straight pipe. Now, if you were going to keep the second cat on for emissions/sound and have the cutout before that, I could see some power gains, but probably not a whole lot (basing this on gains seen by replacing the 2nd cat section with a test pipe, which is basically what you'd be doing). Not trying to crap on your idea, but just want to make sure you think about that before you spend the money. You would also need to make sure you have a pipe connected to the dump (if you did this) so that you wouldn't start burning/melting the stuff under your car with the hot exhaust gasses.

the best gain your going to get from your exhaust is your dp. youll gain anywhere from 30-40 depending on mods. anything replaced after that is just going to be roughly 5 hp. the rest of the exhaust is great for anything the stock turbo can put out for you. i wish i never replaced anything from the cat back and left it all stock besides my dp. theres nothing to gain except a headache. i promise you if you use this car for a daily driver......short term = cool. after a while = annoying and loud. i cant wait to add a resinator onto my exhaust again. lol.

but like said...if you want it for the cool factor/noise then do it up. i think its pretty awesome to have a switch to put you on a dump valve.

You have a 4 inch catless TBE already, if your sig is honest. And you want an electric dump valve? Running 28 pounds of boost? Through what turbo into that 4 inch stove pipe? Sumptin ain't right.

i figure, keep stock down pipe on and be able to have alot less restriction on demand.

This is totally different than just adding a test pipe.
