I see only one little problem. The Exhaust sensor is only in one part of the exhaust flow, so the computer may get incorrect reading etc.

WHAT IS THE NORMAL PRICE FOR A SET FOR I6

Who sells them????????????????????

Yep got em, fit em one day, is 43 outside, so it wont be while its hot.

How do thet sound and feel??? I had a chat to the manufacturers who claim that they use the same processes of manufacture as the Pacemakers, with less advertising. I am thinking of getting a set for my BA XR6.

The tech also suggested that an ideal set-up (in tests) is a 2 1/4 pipe with factory cat and flow thru mufflers. 2 1/4 is enough if you have a good muffler set-up. Any opinions??

if you're using any sort of try-flow or turnaround muffler you'll want the tail pipe to be able out flow the evry ting in front of it.

try flows cancle out the pressure waves in the system that produce the scavenging effect. (not that the length of any road system bolt-on or not is the right length) but after the muffler the pipe has no bearing on power provided it flows more then the rest of the system..

Obviously if it flows less, there will be a power loss

Got a set on the XF and they work great.
Dropped the fuel economy by 2 litres per 100km's.(Drive it like a Grandpa!!)

Got a set on the ZL and they work great.
