Question Exhaust set up???

In about two weeks, I'll have a 02 Altima 3.5 with a T4/T4 turbo with a 3" down pipe, but now I'm looking for a good exhaust set up.

The exhaust set up that I'm thinking is a straight 3" pipe, at the end a dual 2.5 pipe going to the mufflers, no cats, no resonator.

What is better, two mufflers or only one, and why?

What kind of mufflers will you recommend for that set up?

Is it better to keep 3" pipe all the way to the mufflers?

Thanks in advance.

I would call SR20 Development. They can custom make nearly any exhaust you need and have the best recommendations for your application.

interesting....straight T4 on a 3.5L V6 what size T4? what EMS? sounds like the making of a fun ride. have you ever considered running an e-cutout along with a smaller or stock exhaust? i fab'd up a 3.0 in. dp with an e-cutout for my buddies civic. its 3.0 in from the turbine back to the 2.25 in. apexi cat back exhaust.

the car is a sleeper with the cutout closed, it puts down 295whp and with it open it puts down 420whp on pump gas.

the dp looks like this.

Interesting, but not, I never though about an e-cutout.
When you ask about the Engine Management System, what do you mean? I'm sorry I'm new on this, and nobody had talked to me about that.
The size of the turbo is a t4/t4, capable of doing 550 whp
The turbo still on development, but the few pics that I have are in this thread

thats cool....i mean what kind of standalone will you be running? maybe something like an autronic, haltech, motec, FAST, etc. ask the shop and or fabricators, then will most likely have a preference on what they like to run or are most familiar with. you will also want to run some large injectors too, such as 72lb/hr. i think 72lb/hr will provide enough fuel for a v6 pushing 650bhp at duty cycle less than 85%. i dont know if these will fit in the stock rails, so you may need to have some new ones fab'd up. how much WHP are you looking for? oh, and try to fit the widest tire you can on the fronts....something like a 245/50-16 if you can

Do you mean Fuel management? They are using a piggy back by Split Second.
I have 440cc injectors.
Doing some engine/transmition work, I'm looking to get about 550 whp.

i know that the Basch Supercharged NSX's use the split second boxs with their kits. last time i checked, they worked very well with the obd1 cars, but not so well with the newer obd2 cars.....they may be up to speed now,i dunno.
