I figured this might make an okay sticky if we get enough responses. You have just bought a crispy fresh tC and you wish to add more horsepower and torque for the most affordable progression (cheapest things first). Nothing too ghetto fabulous, retail parts for the most part. Also, it is not forced induction time yet.

1. Tsudo N1 Catback, $140
2. Agency Power crank pulley, $120
3. Injen intake, $260
4. Invidia s-pipe, $150
5. MMW headers, $500
6. Complete your pulley set
7. Hmmm...

 

The tsudo N1 catback is 239 the axle back is 140

 

MMW headers are header/s-pipe/cel fix for the $550. Wouldn't need the invidia

Its header, not header(s)

We drive a 4 cyl.

 

Not where I shop for parts, it's not $240. Try Mr. Motorsport.
