I am puttin together an exhaust for my turbo. I have a 3in downpipe already and am going to have the rest fabed. I need to find a muffler with a 3in inlet. Any suggestions would be great. Love the N1s but 80mm is what 2.5 in?
TIA

only one i can think of is the racing beat. I have the apexi gt series exhaust and it is a 2.5 inlet also, that goes into a 3.0 to a 3.5. If you are getting it custom fab, cut off the 2.5 in inlet and weld on a 3 in. only need like a few inches of 3in pipe.

 

i have the n1's on my complete 3" setup. 80mm is just over 3" i think. thats what i wanted but i received the 75mm, which is just a hair under 3". go here for some pics, and go here for the thread i started about it that has some sound clips of the exhaust.

 

Dynomax Round Ultra Flo comes in 3". Borla has one too. both come in stainless. Call summit

Guys, I have a 3in dp and the 80mm N1, nobody wants to do the rest of the exhaust for me. What did you guys do to get yours custom done?

 

You must have failed elementary math.....

80mm/25.4mm per inch = 3.14 inch dia.

If you do the math, two 2-1/8" pipes flow a little more than a singe 3" pipe. Take into account the restriction in the mufflers.... anything over 2-1/2" from the "y" pipe is overkill, but 2-1/4" to 2-1/2" is adequate.

 

not quite overkill. before my full 3" set up, i had a 3" dp to 2.5 in bonez mp and the rp cat back which is 2", i then get the greddy pe catback which is about 2.5" with the 3" flare section (this helped greatly from the other set up), i then got the full 3", and it was a world of difference, best mod i ever did
