turbo outlet pipe - can I bigger w/o porting?

[Jabx]

I've just ordered a 2.5" Upper Intercooler Pipe and throttle body elbow. I'll be getting a MKIV Supra SMIC installed soon, and I was thinking that this would be a good time to go with a larger turbo outlet pipe.

Dejontool is selling one that is 1.75". My question is, can I use this without porting the compressor outlet on the turbo? I'm on the stock 14b and don't really want to mess with porting it.

Your advice is welcomed and appreciated

Sure you can use it. I doubt you'd notice any difference one way or the other. But it is up to you...

I noticed a faster spoolup with my turbo outlet pipe.

that stock thing HAS to be a restriction. Look at that angled part. yuk!

of course that is not a documented response, just a gut feeling.
