SATSFYD Posted October 30, 2013 Share Posted October 30, 2013 What is the difference between the AT and MT LGT 05-09 downpipe? My understanding is there is a shape different to fit around the trannys. Why I ask this is there are more MT downpipes for sale than there are for the AT and I am wondering if a MT downpipe can fit an AT with little moding. Thoughts… **There are two types of people in the world, those who build horsepower and those who buy it. Which one are you? Link to comment Share on other sites More sharing options...
Connor Posted October 30, 2013 Share Posted October 30, 2013 It would take a lot of bending. The AT down pipe has an extra bend before the catback flange. An AT down pipe will fit up to a MT, but the trans mount will be off. Just keep looking around for an AT downpipe or buy new, not worth modifying it.

SATSFYD Posted October 30, 2013 Author Share Posted October 30, 2013 So the front section is the same?

utc_pyro Posted November 1, 2013 Share Posted November 1, 2013 The stock downpipes are actually identical, just have a different bracket. Most downpiple makers choose a slightly different pipe routing than stock, and that ends up hitting the AT transmission. The AT pipes are bent a little wider like the OEM one, clearing the transmission. To answer you last question: Yes, the front section is the same. The back section would be different though. If you buy say a TurboSX front section and pare ti with a perrin AT rear section, that should work. Link to comment Share on other sites More sharing options...
SATSFYD Posted November 1, 2013 Author Share Posted November 1, 2013 Would I be able to pare a TurboSX front section to a stock rear and would it be cost effective? **There are two types of people in the world, those who build horsepower and those who buy it.
