exhaust breaking in

[tanklugz]

hey, just put on my magnaflow catback and well, it hasnt fully broken in yet. i can hear the engine rev at high rpm over the exhaust. i downloaded the sound clip and it was all good, mine but much deeper and louder. how long does it take for an exhaust to break in?

[StreetracerJay]

Give it 6 to 8 months. Then it will get louder.

A few hours of driving should be good for "Break-in". Your burning off the outer layer of coating on the outside of the pipe. This includes oil, dirt, and other contaminants. The same would go for the catalytic convertor.

i am looking for a good exhaust for a scion tc manual i have a cold air intake injen somethink that sounds good and will give some hp gain and addvises

[ZiontC]

Why not stay with injen and get the exhaust to go with your CAI?

i like the injen cold air intake but i am having problems with it its killing my ideal the car sometimes shuts off when i am standing in one spot when i am not driving so i think it could be cause i have a stock exhaust so i am looking for a nice sound exhaust and some hp but if i am going to do that i was gone do the headers and everythink from the engine to the back so let me know if their is somethink nice out their
