You talking about me? I'm one of the first guy in Brisbane/Aust that did it to my celica. And I absolutely loved it. Power wise, never dyno'd but it ran 14.4sec 1/4mile with just intake and no exhaust.
Ok, the celica and corolla are different cars, so the exhaust section is different so I can't comment on the sound or power gains. But on the celica, it was actually quieter than most custom 2.5" exhaust, sound better (I've been through 5 different setup when n/a) and went faster.
And I don't get how everyone on here can say it's HIGHLY ILLEGAL. The cat is still in place, there's a straight pipe going out back, only defect you can get is for noise. Big whoop... And I'm sure most corolla with cannons on here are "HIGHLY ILLEGAL" too.
Sounds much better in person, high revving fun!!!
no not you. its a guy with a red celica.
Hahahaha.. NOPIG?
He's always had an exhaust. It's one of my old exhaust and it's damn loud.
The other red celica that run no exhaust only did so for a day I'm pretty sure until he got defected. $75 bucks and that's it.
haha man i duno what to do !! everyones dissin it !! .. sounds like they have never heard one before
