shorty downpipe and 2.5 test pipe.

[leakslikasieve]

so.... i want opinions. i have been running a 2.5 test pipe for over1.5 years now. never planned on the dp. now i bought the corksport dp and thinking about the 2.5 test pipe..

you guys thing its worth the upgrade to the 3.0 testpipe?

If it's a 3" down pipe, which I think it is, then yes, the 3" test pipe would be a good idea. Since you're dealing with a turbo charged car, you never want to bottle neck that close to the turbo. Bottle necking can actually impede not only power gains, but also the sound of the exhaust and result in a clapping effect due to rapidly contracting and expanding exhaust gases.

yeah i figure ill upgrade at some point. just unsure on what 3 inch i want. my 2.5 inch already scraped on my driveway. i think either turbo xs or su.
