Sry for the newb question but If I already have the SPT cat-back, If I get a catless downpipe, does that make it a TBE?
I thought TBE is just a description(location) of the pipes as a system. TBE=Turbo back exhaust Whether its catless, stock or not has no influence
As long as the downpipe you buy isn't a shorty that doesn't either delete or replace the last cat it will be equivalant to a turboback.
is it this way :- if running no cat :- TURBO BACK if running last cat :- AXEL BACK if running 2 or more cats :- CAT BACK
^^^^ correct me if im wrong TBE is just a description of location of the exhaust system and not what it contains
No, you're absolutely right, technically. Your factory car has a turbo-back exhaust, which includes the downpipe, midpipe, rear centre pipe, and axleback. That said, people do refer to swapping out the stock pieces as 'getting a turboback' or 'getting a catback'... when somebody says they have a TBE, they are referring to having swapped out the post-turbo exhaust pieces for something aftermarket.
yeah, turboback just refers to all exhaust components after the turbo. Catback refers to all of the exhaust components after the last cat. Axleback is just the last bit of piping and the muffler (everything behind the rear axle). If you get a normal aftermarket downpipe, it replaces both the downpipe and the midpipe in that diagram. A shorty downpipe just replaces the downpipe. So if you have say an hks catback and a perrin downpipe, yes you have a full aftermarket tbe. I'm sure many of you have seen this numerous times but again:
for some reason i always thought that an aftermarket DP replaced both cats, but it only gets one huh?
The shorty downpipes only replace the 1st cat after the turbo, not the one in the midpipe since they keep the stock midpipe. Most downpipes will bolt up to the stock cat back or an aftermarket cat back but to confuse things companies like APS and TurboXS make TBE systems where you must use their entire system or it will not bolt up correctly.
Yep. I'm running a TBTWTSCBBAE= turbo-back-to-where-the-stock-cat-back-begins-again exhaust... hhehehe... (downpipe only).
No it does get both! the one on the down pipe and the one after the mid pipe since both those pipes consist of a full after mkt down pipe.
