How necessary is it to upgrade from stock exhaust if you have the apr stage 1+ w/injectors?

 

It's like having a swimming pool half filled.

 

I personally would say its pretty necessary. Theres more fuel/air to be burned off in the combustion process and you dont want your stock exhaust restricting those gases fromgetting expelled.
Even with just a regular chip you should upgrade your exhaust to take full potential.

 

its recommened but i seen a few people run it with out an exhaust system but you are really limiting the potential of ur injector upgrades by not getting one

 

And your turbo will spool up faster...

 

is it limiting or harmful? is it bad for my car.. or just not as good

 

Turbo spool![8D]

 

harmful or not as good as it could be.. I am going to get exhaust eventually.. i just want to get the injectors and stage 1+ first. Can I do it 6 months before or do I have to wait until I get exhuast?

 

It would sound bad if you got one though!

 

no it wouldnt sound bad it would just sound stock
