Injen CAI, Megan catback OE exhaust. The debate could rage all day and night over what makes the most horses and where on the torque curve it does it, but this combinations rumbles in a manner that makes my kid fall asleep.

That alone is worth its weight in gold.

 

my wifes stock Cavalier puts our baby asleep

 

lol funny enough, the quiet and spacious avalon does nothing for the bag of poop. Guess this one likes the noise.

 

Now that is pretty interesting....and has unlimited potential as well..

 

Get the TRD axle-back for even better sound. Stock header + megan midpipe + TRD axle back on an 05-06 = best sound for an N/A tC.

 

why not 07-08 aswell?

 

07-08 have higher compression pistons (9.8:1 vs the 05-06 which have 9.6:1) and sound completely different. I loved my TRD on my 05, and when I got my 08, I hated the sound. The older tCs have a much deeper sound, the 07/08 sound more like a Honda.
