I am going to go turbo eventully but I love the megan catback exhaust sound... so I was wondering which one I should go for the zpi full exhaust system or the megan spipe and catback exhaust......... or could I get the megan catback and zpi s-pipe since the megan s-pipe only had a 2.25 inlet and I heard turbo's need 2.5.

 

My Views

1. Megan Catback
- Read Page 9
https://www.scionlife.com/forums/vie...asc&highlight=
- This catback is version 2 already, but nothing is perfect. I would see what other members are doing to prevent the rubbing.
- $289 est.

2. Zpi Full exhaust
- the only posted sound clip is their shop car with turbo.

- there are people that order thru them and get their stuff quick, while there are some that order and weeks pass by till they get their stuff.
- $499 est
3. CEL?
- there is no proven spipe that eliminates CEL no matter the location of o2 sensor.

 

Hey thanks for the info man! I got one more question is there anychance the zpi or megan spipe could cause a cel? Note: I have stock headers

 

i have the megan s-pipe, its 2.5. i dont know why they have it listed as 2.25 but neither do they. i used my micrometer on the inlet and exit of the s-pipe and its 2.5. just so you know. and you can buy them for about $150

 

if you retain your OEM header then replacing your spipe WILL NOT give your car CEL.
