What you people think about this???.........

a 2.5" for a Automatic Beta 1??...... is this too large and it sould be better a 2.25??.........

for now I´m running N/A.... but I think that next month I will be running Turbo.... so what do you think??....

I will loose a lot of compression?? or not too much?........

Any idea of gains or lost in the power range???

thanks

 

if your going to boost, then 2.5 - 3 inch depending on what psi your going to be running. I'd recommend 2.5

 

2.inch is fine. I don't know what your talking about compression... compression has nothing to do with exhaust. 2.5inch is fine for Naturally aspirated or mild-moderate turbo applications. I'm running 2.5inch on a N/A car and I lost no low end... the exhaust picks up around 3500-4000 is where you start to feel the power gain.

 

Get the 2.5, it will work fine for both turbo and N/A ...

 

UPDATE!!!

I´ve just installed my 2.5 pipe................

so till now I havent ran hard...... but I supose It has to feel the power in the higher RPM right??

thanks

 

Yeah, it'll be able to felt more middle-high.

 

Sounds mean..right?

 

It didnt change the sound........... i thought that it was going to change, but no..........

I hope everything is ok........Lol......

 

Did you have a custom crush bend exhaust or did you buy an aftermarket exhaust?

 

Did you keep the stock muffler?
