so i put on my meagan mid pipe and Tanabe concept G today. i replaced the TRD exhaust it came with. i really like the TRD tone and now i feel that the Tanabe is alittle too loud for me. im kinda scared to hear what it might be like when i put the WR header on tomorrow. do you think that because i have a S/C on it made it louder? after i get the header put on i will probably get a aero 25 to quiet it up. the guy at the shop told me that scions come with a decent cat and i can just put that one on the mid pipe. it wont be "high flow" but we'll see.

 

i wouldnt use the stock cat . the main cat is in the header . then the secondary cat is to small to do anything useful for emissions
