One of the guys on the list lost hp when he installed a set of Broadfoot V band headers. Nothing like a couple of grand to go backwards.
I can see how this could happen. The idea behind the header was good but the execution was poor.This is is why the SFR stage 2 header came to life.We knew it could be done better and for less money!

This is correct, I was not referring to SFR exhaust. I have not seen or used any of SFR exhaust therefore I have no idea how good or bad they are...

Tim - do you think there will be an oppotunity to get a small group together on the header? I am kind of capped this year in my car spending, but there is always next year. I was impressed by the customer service and quality of parts/welds/etc. I figure the header and manifold will be some of the last parts I do but the ability to drop them in 1/1000000 the time is very appealing. I just dont think we can get 10 people to drop that kind of cash.

Thank you Fast, for clearing that up. Your post might have given people the wrong impression.Judging by the amount of hooray posts about the SFR exhausts systems over the years, I am sure you have to have some sort of idea of how good are exhausts are;^)

I never judge a product till I examine it and test it myself. I have seen pictures of your products, and they look nice.. As for performance, I prefer to do the testing myself... Maybe soon

Reviving a very old thread I understand the SFR manifold cannot be used on a RHD car. Here in the uk that is a problem but I wondered if anyone could tell me a little more about back pressure on the 944 turbo especially when capacity is increased (in the 3.0 conversions) I note SFR have a 3.0 turbo project car.
Have any tests been done during development to establish whether back pressure is an issue with the standard manifold? If so how have SFR reduced this problem with their exhaust?

I saw no improvement at all in power through the rev range by changing from a .80 hotside to a 1.00 hotside. Which suggests that this isn't a problem but I wondered if someone had looked into it and could tell me?
