downpipes im talking about is when you take the cats off you need to replace it with something right?so my guy built 2 cust pipes to replace the cats (which are called down pipes) but you know so much about mods i thought you would know that :-)

 

sounds like test pipes to me

 

also called test pipes too same thing mystakin and i thought that would add a few xtra ponies

 

Downpipe is a pipe that goes from the hot side of the turbo to the exhaust. Some downpipes delete the cats, some don't. What you are talking about are called test pipes/cat delete/straight pipe. So before you call someone a retard, I suggest you learn what you're saying.

 

well you just said some down pipes replace the cats!!!!!!!!!!!!!!!!!! hello!!!!!!!!!!!!

 

Helloooooooo downpipes come from the turbo!

Helloooooooooooooo!

 

now that were calling it the same thing that should give also increase another 10hp soaltogether not so far off from 60hp exspecially after i get the uprev tuning done to it tomorrow

here. Since you are a selective reader.

 

ipitythefool since you know so much about increasing horsepower and mods i would love to hear what you have done to your car (if you have a G37?)

 

IT's not the same thing. Downpipes connect the turbo to the exhaust. Test pipes connect the headers to the exhaust.

And you made nowhere near 60 hp. Keep dreaming.

 

Read my sig

 

these dont connecrt from the headers to the exhaust these replace the cats in the back (the headers are in the front)

 

Do you even know what you are talking about?
Ughhhhh

intake>engine>headers>cats>exhaust.

Replace cats with test pipes? Omgz gaiz look where they go!!

 

tempted to lock

 

Du it. Maybe he understands downpipe=/= test pipe now and that he didn't make 60 hp.
