Right now im running a Tanabe downpipe that is 2.75 inches would there be any difference if i changed to a 3 inch

 

IMO, if you have already invested in a 2.75, it doesn't make sense to spend a few hundred more and buy a 3 for the minimal gains. However, if you haven't invested in any yet, which isn't your case, I'll go with the 3.

 

I'd always suggest the 3"... even on an otherwise bone stock turbo car. However, if you already have the other, I'd not be breaking my back to change it.

 

judging by your mods it wouldnt make much of a difference

 

so i should just keep it

 

On a stock turbo'd evo you'll lose low end tq going to a full 3" DP....

 

Yes...

 

Jesus Christ! It is a conspiracy today...

That is not necessarily correct... 99.9999999999999999999999999999999999% of the time, incorrect.

 

With all due respect, I beg to differ with you !!!!

 

I've had this stashed away for people who believe in the back pressure myth for a few years without throwning it out there... now I think I've had use for it 4 times in the last few days. It's easier than typing out a long winded post every time though...

Back it up with proof then.

 

keep it, i see no reason of changing.

 

To reiterate, since he already has it... might as well keep it...

 

If he decides that he just has to get a 3 inch to see for himself, he could always sell his on here or via ebay and then take the money and put it towards a 3 incher!

 

probably not gonna matter unless your over 600whp...
