Sup fellow boosters...I'm hoping you guys can help me out.

I was wondering how these exhaust manifolds differ as far as their performance gains. I'm basically looking for the pros and cons of both to help decide which manifold I'm going to use on my set up.

I'm keeping my internals stock, but I'm trying to get the maximum power and efficiency out of each part I buy. Here's the set-up:

Precision or Garrett T3/T4
Custom Welded Piping
580cc injectors
Honda S300
GSR Cams
Walbro 255HP Fuel Pump
Moroso Oil Pan w/STEEL BRAIDED oil return line
??? Exhaust mani
Tial 38mm Wastegate
Greddy Type RS BOV
3 inch downpipe and exhaust
AEM Adjustable CAM gears
AEM Pulleys
AEM Fuel Rail
And a very good tune @ 10.5psi

 

i'm switching from a topmount to a shorty/quick 4 manifold because i'd rather have the quick spool and a little less top end power on the street.....if the engine is stock, get the shorty, if its built, its a toss up, but more towards the ramhorn

 

Excellent--so the top-mounts and ramhorns are more for the all out, top end power for more built motors, correct?

Yeah, I'm looking for a relatively quick spool, but still have a nice power gain over a cast log mani.

Anyone recommend a particular tubular shorty?? I was looking at Lovefab. Any other recommendations?

 

^^^^

 

the lovefab stuff is very well built.. so you wont go wrong there..

and for your app, save the money and do either a shorty or a cast inline-pro or something...
