building a street ported t2, Take a look at my exhaust and let me know what you guys think:
RB 3in Down Pipe to Custom 3in piping to Higflow cat (suggestions) to N1 or another muffler (again suggestions)
Should flow good, I would like to keep the 3in size through out.

ditch the cat unless you have emmisions and a Apex N1 should do just fine

 

I dont have emissions problems but I had a dual n1 setup on my sp NA and its was SOOOO LOUD you have no idead. RB header back via 2.5 inch pipes to dual n1s. You could scream behind it at 5000rpm and not here yourslef. I ended up having to and resinators. Trying to avoind that kind of volume this time. Do you think it will be that loud.

 

i don't think the streetport will make too much of a difference compared to mine, but i have a to4b turbo into a full 3" exhaust with 2 n1 mufflers, its pretty ******* loud.......but for the power i'm getting, i can easily live with it plus you can always get the silencers for it if it bothers you at all.

 

turbo is way quieter then N/A ...

you could pick up the RB pre silecner too. not much different between that and a cat.
