For those who got the Tsudo N1 exhaust (catback) on their Scion tC's. i don't know whether anyone of u notice that after a couple days u had installed the exhaust, the sound will become more deeper, smooth down a little and a bit quieter than before???

(please let me know for those whom have noticed this)

 

It's natural for all exhausts. Exhaust burn-in.

 

it's a lot quiet than b4.. i mean not that noisy it'a like the exhaust really smooth down...

 

Normal

 

also anyone of u notice that when the speed is over 70 mph and u take the step off the gas, it will sound more louder than while ur feet is stepping on the gas...

 

That's probably the engine braking shooting the rpms up, or it could be you just hear it more from reduced engine noise.

 

phillysky, happens to everyone. including me. and i have the tsudo n1 exhaust.

 

yup i have the tsudo N1 and its the same its all good and normal

 

ohh ok.. thx for everyone's reply... btw, the exhaust is realli awesome... but i heard someone said that they're not gonna produce any of those tsudo exhaust anymore?? is that true??
