hey i was just wondering how many hp does the TRD axle back exhaust actually add to an 05 scion tc?

sorry for the n00b question lol

 

1 hp.

 

save some money and buy a full cat-back system

 

doesn't really add any hp, just sounds like it does. take it from a guy who has it.

 

Honestly, I tihnk it is one of the best sounding exhuasts out there. I loooves it. Though id rather listen to an STI mmmm

 

so the exhaust doesnt add hp at all lol that sux i was told it does lol

how many hp does the catback system add? and how much is it?

 

not alot, maybe like 5-10 whp.

 

you won't get 10hp out of a catback. Combined with a nice header might net you 10.

 

i doubt that....i wouldn't say anymore than 5whp, and thats on the generous side....most exhausts are there for the sound......difference you'll feel in more in throttle reponse than anything else....its true that if you pair an exhaust with a cai, and header, you can net 10-15 whp, but thats as a combo

 

TRD + Custom Piping FTW! :D
