somewhere in the near future i'm putting a 406 into my camaro. I'm trying to budget everything needed for the swap right now. The exhaust (stock except for flowmaster crossflow muffler) is deffinitly too small for the motor, but i wanted to know what you all think is enough for that motor. Dumps? Mufflex? i think whatever i go with, the muffler will be hooker aeros. what do you guys think?

 

it's really up to you.. single or dual. I'd probably do a 3 inch to 3.5 inch single, depending on how radical you're getting with that motor. if it's an all out drag car I'd consider a 4 inch system (pushing 500 hp+).

For duals you could get away with 2.5 or 2.75.

 

well i'm guessing 400hp and pretty mild on the cam side of that. i'd like to go dual over the passenger axel but i'm not sure if i can budget it or not.
