3in turbo back good or bad

[jred321]

yea our o2 housing should help prevent that as nobody with 3" has suffered from it yet, but it could be a concern if people start to push more power

 

[hukster00]

hmm but we dont have o2 housing, our o2 is in the mani , i gess you mean the spipe

 

[SherbertRocket]

so 3in is the way to go even if i were to leave it stock for a while would i loose torque and gain hp or gain both?

yea that's what i was talkin about, the equivalent of the o2 housing on a dsm

 

[hukster00]

what ever you decide you will make hp/torque

The size of the motor and the size of the turbo are whats going to determine how much back pressure you produce in the xhaust system. With the smalll 2.0 liter engine and the output of the turbo, you're not going to see any gains from a 2.5 to 3.0 exhaust. Go with 2.5 inch. You have more room to drop the car also, if you AutoX.

SherbertRocket - The biggest advantage with our system is that it's a TRUE full turbo-back system. A 3" exhaust will maximize the pressure difference throught the turbo, thus minimizing lag.

Not sure where you get the 400hp numbers but an unmodified 1.8t GTI gains an extra 5hp between the same brand 2.5" and 3" exhaust systems. A chipped GTI gains and extra 10hp between the two. These dyno runs were done back to back.

I have a 2.5" Apex DP and 3" Thermal exhaust. I like the setup.

 

[hukster00]

i have TRUE full 2.5 turbo back and i like it to

I have a 3in dp and exhaust with no cats. I suggest 3in.
Bigger is always better

Sometimes too big hurts....

Wells lets throw a 4 inch on than.

If it don't fit, push harder.

 

[SherbertRocket]

what about the new insidious 3 in back or apex 3in back

 

[gcotton]

This aint no damn SUPRA

I am having a custom 2.5 leaving the turbo, then it tapers into a 3" inside a hi flow cat. Then the 3" the rest of the way back. Makes for easier fitment..
