Collector theory question Yeah another damn header thread..
I have SLP Tuned Length LT's.. The older design. Had em on for 6 years now. I was reading that some people picked up at least 50hp with QTP LT's and a tune. I actually picked up 46hp with the SLP TL LT, Catted Y, Borla CB and a tune.. Also with a lid and P+P'd TB.. This was back in 04 when I installed them.. I was very surprised to read that mine perform up there with QTP results.
Anyway.. I was wondering WHY these headers have such a snub collector on them. After reading thru the links posted in the ARH vs Kooks LT threads. I understand that with the LT LT's the pipes are designed to be of unequal length to space the firing order and pulses apart so they arrive at the collector following each other instead of fighting each other.
I take it this is why some have a merge, or HV collector. But Does the SLP TL LT design just not need any kind of venturi or merge collector?
Pic from Google. This is what the driver's side header looks like. Note the stubby collector.

^ Yeah, I've gathered that much.. I'm just looking to find out why the tuned length headers have a different collector than the "long tubes" that are more popular. ie; QTP, ARH, Kooks, Pacesetter, Hooker etc etc..

^ That is true. Not sure if it is needed for tuned length LT's though. The tuned lengths are designed to have the pulses of the exhaust follow each other instead of arriving at the collector at odd intervals and sometimes fighting each other.
