I currently have a 3"TBE but thinking about going back to stock catback with cutout. Help me out here give me some opinions.

what are your future plans for the car?

i have a cutout to stock catback. but i'm thinking about switching to a just a full 3 inch for autocross classing reasons.

I think it would be cool to have DP w/ e-cutout. sleeper then all of the sudden rape turbo spool. It could really trip some people out. I am going to switch as soon as I find somebody that makes a good cutout. I hear QTP blows and the motor always goes out on them.

the needswings is awesome and the powerplate has so far been great nothing wrong with it

and yeah its pretty fun .... opening and closing it people look at ya like WTF.

Any power difference?

I really dont know my plans yet I have several other mods right now prob next step would be big turbo.

Needswings is the one I'm going to get. I do not recommend QTP. FTL!!!!!

I have the Needswings + McCord electric cutout setup on my car with basic stock turbo mods. I posted the following thread earlier in the year which shows before/after dyno results from opening the cutout. I picked up a ton of torque with it open.

Before/after dyno gain with cutout

Needswings if you go with a cutout. had one on my car for 4 years. E-cutout too. Worked great. Loved the sound, although it is loud.

Switched to a Maxfab 3" dual tip TBE with a resonator and cat instead. Still loud but it sounds good.

Changed turbos though so I don't can't compare spool time with the different exhaust. The cutout will spool faster though. Less back pressure.

Will the cutout in any way lower the performance of the car when closed via turbulance?

Im not an expert but I would have to say yes. Since doing the dump tube reroute kills performance because of turbulance. With the cutout, the exhaust starts down the tube then gets stopped and has to back up to go out the long tube.

this is kinda true in a way... when i put on my down pipe its a 3 inch i noticed gains over the stock dp big time and then more gains when i open it... so as far as that goes you'll notice more power... the true part of this would be that i can see the turbulance causing some power loss over another 3 inch down pipe that does not have a cut out but if your stock your going to have power gains by switching to a bigger downpipe no matter what
