06+ WRX OWNERS READ: <u>On the 06+ WRX there are boost spike or creep issues in all cases with the use of an aftermarket downpipe or turboback.</u> This is because the 2.5L engine pushes so much air. Even with the internal wastegate fully open not enough air can exit to stop spinning the turbo, the result is boost creep or boost spike. With the 06+ WRX, unlike the STi, you cannot fix the problem by just porting the stock turbo wastegate. We suggest porting the stock turbo wastegate AND getting an engine management system to help fix the issue like a UTEC or AccessPORT. With the added costs this will entail 06+ WRX owners may want to consider waiting to get an aftermarket downpipe or turboback after they have upgraded there turbochargers or they may want to consider getting a cat-back exhaust only.
04-06 STi OWNERS READ: On the 04-06 STi there are boost spike or creep issues in all cases with the use of an aftermarket downpipe or turboback that uses a bellmouth or external dump tube design. This is because the 2.5L engine pushes so much air. Even with the internal wastegate fully open not enough air can exit to stop spinning the turbo, the result is boost creep or boost spike. You can fix the problem by porting the stock turbo's wastegate passage (any exhaust shop should be able to do this or it can be done at home) or you can get an engine management system to fix the issue, like a UTEC or AccessPORT.

Bye.
Subversive.

Die Firma HMS bietet seit heute auch eine 3" Edelstahl-Auspuffanlage für den STi 06 an.
Gegenüber der Bj. bis 05 gibt es bei der Serie im Bereich Downpipe gewisse, maßliche Veränderungen.
Wer bei HMS die Serien-Downpipe belassen möchte, der bekommt zur Anpassung eine entsprechendes Zwischenstück geliefert.
Die Geräuschmessung bzgl. TÜV-Eintragung erfolgt aber erst Mitte Mai bis Mitte Juni.
