4-1 or 4-2-1 header for a supercharged tC
I ordered the MMW header/s-pipe for my supercharged tC. As I understand it, the 4-2-1 design gives great gains throught the powerband, whereas 4-1 gives power at the top end. For a supercharged car, would design would be the best?
I also just got the DraXas cat-back exhaust, so I'm thinking the MMW header will give me some sick gains.

with the trd supercharger the 4-2-1 will be fine because you dont need the extra top end due to the design of the supercharger. You may get lucky but i would not expect outrageous gains from the header and exhaust, maybe 10hp, however the header s-pipe combo from MMW is very nice. good luck and i hope you like it

I know you didn't gain as much as you expected from your setup, but I am still curious as to why your car didn't respond well to the mods you put on. Has to be some kind of flaw.

I actually went 4-1 because of how the vortech sc works. It focuses boost in the top end, therefore a 4-1 was exactly what I was going for. I ordered in a megan with s-pipe and next week ordering a precision muffler cat back. Should give me the flow I am looking for

Understood You will be happy with what you bought as will I. Overall the flow restriction with the stock cat in the header is just sucky. No matter what header design you choose, more power will be available throughout the powerband. I just wanted to focus overall flow in the top end from 4500-redline to take advantage of the way the vortech makes boost.

Well i hope everything goes alright with the install on the MMW header. It in my book is the best header out there, just hope you dont have to install it twice like i did. The one i got had fitment issues, and had to be exchanged out for a new one.

Im curious to see how the MMW header does as well...right now Im running the alphawerks, spipe, 30" resonator and the TRD axle back with the charger and its pretty nice. I love how the TRD sounds
I wanna do a custom mid pipe setup, but I dont want the car to get any louder than it already is.
