Exhaust systems
I just started looking at exhaust systems. In a "turbo back" installation, does the cat stay or is it removed (I assume removing it is a big no-no). If it does stay,is there still a performance gain and a cooler EGT temp ? I see stainless systems and also aluminum. There is a big price difference. I am sure that the "buy the best that you can afford" applies, but is there anything wrong with a cheaper system? Most of my research has been on the MBRB pipes, and Banks seems to be a big name. Any suggestions would be appreciated.Tom in NorCal

I just installed a MBRP T-409 Turbo back system. The factory cat was retained but a "test pipe" can bought that will eliminate the cat. The install was straight forward. I had a little problem with the down pipe but patience prevaled. The sound is not much louder than stock but it does have a nice low rumble. I don't have gauges and can't report on EGT's. The fit and quality were better than average. With the Predator set on 65 the truck is unreal!Sam
