urs4 exhaust

[dainys]

hello ,
What do you think about exhaust like this: custom 3" single pipe from turbo, at the back "Y" type connecting from 76mm to 2x55mm, and urs4 stock rear muffler.
Will this exhaust be restrictive if I want to have 400 hp.
Stock rear muffler has 2x55 pipes and 2x45 inside restrictors.

With that power level you are better of with 3" all the way.

I run just what you describe. I have about 400hp. Eg top out rs2 injectors. No problems. Was told the s4-s6 could do almost 500hp from the cat back.
