I want to put an exhaust in my car but i want something that sounds deep and clean... what do u guys recommend?

 

You don't say what model you have but if your changing the muffler only
then check out Magnaflow.

 

I want to find a cat backto fit a 1.8 SE+. All I have seen say 2.0, 2.4 only...

 

sorry i have a caliber R/T 2008. I want the whole exhaust from the headers back if they have it.

 

The header on the AWD RT is different from all other models
as it is offset because of the AWD,I don't believe there are
any aftermarket headers availiable.
The RT FWD maybe different tho,find a good muffler shop
and tell them what you want.
