Turbo Or Cat Back?

[jezzathejerm]

I have an R33 Gtst and wanted to know what was best for my car?

A cat back exhaust or a turbo back?

What does everyone think?

[R33_Rob]

turbo back for sure

[R31Nismoid]

turbo back... its logical to remove the most restriction possible.

And restriction starts with the turbine housing and anything after it

Turbo back.

Cat back refers to the exhaust from the catalytic converter to the rear muffler (does not include the cat).

Turbo back refers to the exhaust from the turbo to the rear muffler. The whole thing basically.

So in essence,

Cat back = cat back

Turbo Back = dump pipe, front pipe, bigger cat, cat back

as your question asks whats better for my car... id say cat back because it helps keep your turbo running closer to factory conditions where as turbo back alows for more turbo rpm quicker spool up and better performance

correct me if im wrong please!

cheers and good luck

I don't get what you're saying Jenkies? Factory specs are quite restrictive and don't allow the turbo to perform as it's meant to. I dont see what's wrong witg quicker spool up and better performance?

If anything you DO want a turbo back, as it will be less restrictive, the turbo will spool up quicker and possilbe gain a psi or two due to the turbo being able to spin more freely.

Think like, the turbo can't get in more then it can put out, so if the exhaust is restrictive and the turbo can't spin those gases out, its only going to spin as fast as your exhaust will allow, so it won't be working as best it can.

i think he means that it is better for his car as in condition wise not to over trash the car by putting in a turbo back as it is less restrictive than the factory dump pipe?

and ofcourse TURBO BACK!

you are wasting precious time and money on a catback. tb systems have become quite cheap, just have to keep your eyes open.
