time for a new eshaust system

[DownunderGTiR]

finally my stock eshaust system has given up on me due to time(leaking) so i figure it a sign to get a new one.
my power goal is somewhere between 450-500hp with a gt3076r
and i been reading around and people suggested if you were looking for 500hp you would need a eshaust system of 3.5in in size.


i'm wondering if a 3.5in downpipe would fit on to the R without any or major modification?if not what is the largest size that could be fit?

i have never came across 3.5in eshaust kit for R before is there some i havent hear of?

can anyone recomment me to a place which can custom make what i'm looking for?

how much i'm looking at paying for a full system?

thank you very much:yawn: ps. sry for the long post

3 inch will be fine for that power 3.5 is really only needed if going above 600-650 so with a 3076 3" will be fine

If you're in Austrailia, have you tried CES? They do some (expensive) 3" stuff.

I got my janspeed from lionel at ninja tune factory or www.ninjatunefactory.com you should probably email him for the prices as i've forgot
