Hey guys

I read a thread here that some of you guys got a bosal/brospeed header on your car and you liked the gains. It supposedly gave you more torque.

Well I found this 4-2-1 design on ebay for $150. I was wondering if you guys think this is just as good as the bosal one. Is it better, same, or cheap/bad? I want something that gives the same gains in torque (and I guess HP too) as the Bosal one. Let me know. Thanks.

But the way, I have an auto tranny. I heard the 4-2-1 design is the best for us since the AT need as much torque as we can get and it is better for mid RPM ranges (street use) compared to a 4-1 design (high RPM gains for track).

MODS:

HRC 16g turbo kit, Spearco custom FMIC, Custom IC piping, VT rebuilt engine: Custom 8.8:1 compression CP pistons, Eagle connecting rods, Melling oil pump, Clevite bearings, 370cc injectors, Vortech S-FMU, Apexi N-1 catback exhaust, AFX UDP, Autometer boost gauge, fuel pressure gauge, EGT gauge, Corbin's digital A/F gauge, Tokico Blue shocks, Tein springs (1.5" drop), 18" Konig Verdicts rims, VIS stock-style Carbon fiber hood

anybody?????

If you don't have it yet, I'd seriously think about getting an AFX underdrive pulley than a header. It's around 160 bucks at ptuning.com. It's much more proven to give any significant gains. A lot of people would agree with me here. Plus, if you're going turbo, you'll need to get rid of that header anyway. With the AFX, you get to keep it.

I heard that people with ebay headers said they crack easily.

That is a 4 into 1 design. Will give you a little more top end but not worth if you don't have cams, cam gears, UDP, higher compresion pistons, or NOS. It will flow a little more than the stock, but if the motor can't suply it you will just lose torque.
