Rip is in the northwest , Orogen I believe. I just orderd the 5" from rip on friday , and he gave me a great price on the phone. You should call him. This is the second time I have delt with him and he has been very helpfull. I would highly recomend getting his kit.

 

I don't think 5" is unnecessary in some applications...

Id love to see some dyno charts of a REAL person changing the exhaust from 3 to 4 to 5".

You cant add a firehose to the end of your garden hose and expect to get more water out of it can you?

It just drops the pressure at which it flows.

Turbulence is reduced and especially when the exhaust is larger than the turbine wheel, it reduces efficiency.

Things have to be done in tandem, only hurts getting an exhaust larger than your turbo outlet.

 

Put some more pressure behind that garden hose and you will get more water. Dump more fuel into a CTD , and you will get more exhaust.

I am also going to look into the MBRP 5" kit , i hear the factory is in canada , so maybe i can buy one from a distributor and get it direct shipped from the factory.

 

Well , i did some more checking and i think i am going to go with the MBRP aluminized 5" , and get a polished 6" tip for it. I can get it from piers in can $ cheaper than i can buy one anywhere in the USA in us$ (if you convert the $).
