My friend was telling me about a dump tube. Ive never heard of it before but he says that it is a tube right after the manifold that will let me switch from stock exhaust to basically an open tube right under the motor that can be switched from one to the other by a valve that is controlled by a switch in the car. What do you guys think about this? I want my car to be really quiet for normal driving but wouldnt mind it being really loud for those short periods when im racing.

 

well I have a something similar to what you are talking about.... a regular dump tube is not controllable but my setup has a switch in my car

thanks. how much did the setup cost you? and whered you get?

 

im trying to see if that or a turboback wold be more worthwhile.

 

186 for the cut out and y pipe assembly (includes wiring and switch) from quicktimeperformance.com...
welding and wiring price varies due to whoever welds it and wires it for you

 

ok thanks.

 

Exactly where were you planning on "dumping" it? If you do it too close to your engine, you're gonna lose all torque and risk getting elements inside the engine. If you have it at least a little bit down from the manifold, you should be ok. Still a loss of torque, but if all you want is sound, great. But if you wanna win...

 

The loss of torque may not be so bad once he puts on that turbo. Now if he was going to be running that NA, bad idea.

 

i dont want sound, i want power. how much of a loss of torque are you thinking it would be urban?

 

these are awsome, by brother-in-law has a 87 grand national w/one on it. it's sick, the turbo sounds great. thanks pqmike for the website to pick one up. do it, you wont be disappointed

 

i offered a website?

 

What's the chances of that making life difficult when getting inspections?

 

we dont have inspections in FL

 

Since you have a turbo, it will drop back pressure which will allow for quicker spool up times on less boost creep. Good investment for 186 bones.

 

sounds good, i really got to look into it
