hey, im getting ready to have a guy weld me a test pipe for my t6. will a free flowing exhaust (no cats) and a three inch downpipe cause issues with different back pressures and fuel trim controls as far as drivability concerns?

 

1. Do not go without CATS. Why? Because is some places it is illegal also it will cause problems without them.
2. Your a T6 you have two downpipes so you will need two 3" downpipes.

 

3" mandrel bent downpipes to a 2.5"-3" mandrel bent catback system with free flowing CAT and muffler such as a BORLA or MAGNAFLOW.

 

yes.. and i know that i have two downpipes. and all my life ive never had and issue with whoever the hell regulates catalysts and checks operation of or to see if you have one. ive been gutting cats all my life..i live in kentucky bro.. no cat cops here..lol.. my question is will it give me more power free of quirky computer controlled issues? i know that obd2 cars to run great have to have about everything oem.. and the comp system on my car ive heard is super picky. ive had like 4 experienced guys tell me itll be great and awesome. .. i just wanna get a little more input before i make a decision and butcher this bitch.. .. and yes i have been drinking a little toniget.

 

DO NOT GO CATLESS. YOU WILL RUN INTO PROBLEMS.

 

WHAT PROBLEMS!! just let me know.. will the car not run right? if it is a problem of the check engine light coming on because of o2 sensor 2 bank 1 and 2 then i am not worried.. if you have seen other problems then let me know.
