Well got a custom made downpipe from before that fitted onto my n1.. now i got a 3 inch thermal.. how do i make the pipe go from 2.5 to 3inch so i can weld the flange on? possible solutions? i've heard of a cone like thing that you can use and just cut from what you need... thanks

 

not sure if this is exactly what your looking for but may help..... Its a 3" to 2.5" transition...

look interesting......how much does this usually run ? where can you get them ? These would be good for ppls who want to have a 3 in DP w/ no AC. But how do you screw the bolts in, Looks tuff.

 

Not sure how good it works...i just got mine the other day...wont be builidng the downpipe for a few weeks....... THe link under pic has the info and price.

 

PERFECT thanks a lot!..

 

All you need is a reducer that goes from 2.5" to 3".

 

I just got mine at atp turbo yesterday. Great service and good prices.

 

wow i could of used one of these when i did my exhaust

 

I have a 3in. down pipe with a/c. Mine was custom as well. You have to buy 2.5 to 3in expansion pipe. It will work fine.

 

well guys what do you guys think? should i just go ahead and do a all the way 3inch downpipe.. what are the gains? because i have a custom fabricaed 2.5 inchdownpipe with a flex on the end made by inline pro.. should i just go ahead and cut the whole thing and make it 3 inch, inwhich i have to buy a 3 inch flex too.. is it worht the trouble?
