I'm planning to use pineapples large street port template on a S5 TII rebuild I'm doing and I'm not quite sure what exhaust template would be the best choice. I hear if you use too large of a template then you can expect lower torque on the low end. They have the REW template and the BP/PP template but they look quite large and the medium looks like it would be to small. Any advice fellas?

I'm not knowledgeable about porting techniques, but don't be afraid to ask some of these companies over the phone about the topic. Pineapple is very knowledgable and willing to answer any questions you might have over the phone. I've had the same experience with banzai, Atkins, and turblown.

I'd also see what people say here too.

 

Here are some exhaust ports:

 

I have some experiance using pineapple medium profiles on my road FD with a t04r single setup.

My T04r is a divided 1.00ar turbine on a divided ebay manifold, it starts to push positive boost by 2500 and hits full boost (12psi) by about 3600rpm.

I can't believe how well it spools with this porting!

Low down torque and cruise seems unaffected, but it is worth noting I have kept my secondary butterflys, so the larger secondary ports are closed under vacume, I chose to do it like this to hopefully keep my low down torque.

Hope this input is of some help.
