Rite now on my tc is a 2008 White Scion

i have
TRD Axle Back Exhaust
Injen CAI
Headers
AirRaid Throttle Body Spacer


im wanting to change mi exhaust and the headers that i have right now.
is there a big difference in a catback and a axle back.
becuz im looking into a catback rite now but dont know wat would sound good and deep.

and for headers, what do people mean when they say they get a s-pipe with it. do i need a s-pipe.

What is yalls suggestions.
I was looking into da Catback Drift Spec and for headers maybe weapon r?

what do u guys think
feedbacks thanks

 

header not headers. um yeah there is a big difference a catback has a midpipe and an axleback is jus an axleback, as far as performance gains no theres not major, Bolt ons are pointless for the tc little to no gain literally. S-pipe is the pipe after the header. so if u had a full exhaust it would go Header-Spipe-Midpipe-axleback. Drift Spec is an ok exhaust i like it, other wont but i think the angeled look is played out, and Weapon R/MMW header is probably one of the best out there bc it comes with its own s-pipe (4-2-1) but that set up would make it a full header back exhaust system. you can keep the TRD axleback and header u have now and jus make it a full exhaust by getting a s-pipe and midpipe
