Xforce Exhaust Thread

See there ya go 2 guys with diff opinions

I reccon the 3.5 split would have the same if not more volume than the 4 anyway

correct me if im wrong

Not if the wastegate is held closed, if it is the system would just be using the 3.5 pipe.

[Covesy]

Why would you need a 4" pipe with the gate closed. That's all the reason why I think the 3.5" would be better

[straughsberry]

The answer to that is - time to go external gate!

I was considering getting this but have no idea what im doing or looking at.. Dump pipes???? They from the back of the turbo?? or is that a screamer pipe? Anybody got any pics??

[bjc]

Yes that's the exhaust pipe from the back of the turbo that dumps the exhaust gas. Check out the pics on the xforce website-XForce - Performance Exhaust Systems

Screamer pipes are a small pipe that dump straight from the wastegate to the atmosphere.

The only way that you can be 100% of the difference is to do a back to back test of the dump pipes on the same car, same dyno etc. Overlay the power, torque and boost and soo how they differ?

Has anyone actually driven two cars with similar power and been able two tell the difference between the two?

[Wenier]

Get whatever takes your fancy. Personally I'm going to get the 4" dump as I believe it will be better for me, and remember you must tune so no matter which one you choose you need the tuning money at same time.

[bjc]

I had no preference and the split dump was available at the time so I got it!

Ive read that its twin 2.5", is there any way I can get an adaptor for my cat as its a single 3.5" outlet?
