Oh yeh all this is done with no accessories on i.e. Radio, AC, wipers..

[Mello]

The standard exhaust on the 1ZZ is 1.75" ... we have a 2" system from the resonator back to an Ultraflo muffler (in addition to a K&N panel filter, but no ECU reset) and there's been a noticable improvement in the bottom end.  It seems like the auto is hunting a lot, but I think its always been like that, its just louder and more noticable now.

Mind you, you're the only person I know of that has the Stivo exhaust on an auto ... anyone who has done the same would be great to hear from.

Erm... what's hunting?

Hunting is when the transmission is trying to work out where it should be for a given situation, it might be locking and unlocking the torque converter in overdrive, or it might even be shifting between overdrive and third ... usually happens on some sort of incline.

well thats what i do n it works :P

[CORZZA]

just a question?

hw do you know it works? what signs are you looking for?

[justin_es]

know if what works

the torque converter

[shmicko]

so would it be best to go with just a muffler? Given there isn't any gains on our auto's with a cat-back setup.

[justin_es]

lol im sorry but your problem cant be that big 2 years on and your only just replying now if you just want a half descent note go a muffler

if you want a slightly bigger gain in power then nothing go full cat back

I just got a 2.25" cat-back system fabricated and fitted. With just the CAI my car was feeling laggy down low. Now it feels like the car can breathe much more easier and the engine rev's out quicker.
