ok guys here's the current set up on my car i have a megan s pipe, megan mid pipe, and trd exhaust and i already set off car alarms. i had my dc headers on for a day and took them off in a matter of hours due the fear of gettin a ticket.... i wanna put them back considering since the factory manifold is so restrictive. any tips to keep the noise down??

 

You need a serious resonator welded into your mid-pipe.

 

any specific brand or length for the resonater wat about a high flow cat?

 

start with resonator.....couple of great chioces out there........Aero 25.......Vibrant........Thrush........

The thrush is dirt cheap and probably the most commanly found in exhaust shops.....Aero and Vibrant you will need to pre order online and take into the shop.....

Magnaflow also makes great products........

remember header makes rasp and loud noise.........resonators take the rasp and volume out.........

High Flow cat will take some noise level down too,but they are spendy and will not make a lot of differance,plus if yours on the car is not trashed no need to replace.
