Just curious- how many here with after market DP's run test pipes often or regularly?

Not me, have 200 cell high-flow DP cats. Don't see any reason to.

Default Thanks- I wonder how much power there is in test pipes. Also, how much additional sound...

I really like the current volume with ASP DP's and a 3" milltek.

Default You should have 200 cell cats as well. Will gain some power (est 15-20 WHP) and noise w/test pipes

Default Thanks- I do have the 200 cells I believe. Sadly....

after being on the dyno I want to see what the car would do with good IAT(looking at water/meth and ASP FMIC), test pipes, cut-outs, and race gas on a race program.

When I rationalize it this makes absolutely no sense, becase I will most likely drive it with CATs and on 92. I guess I could ge the water meth and the ASP unit but even those most likely aren't necessary.

this thing is like a freaking drug.

Default It is very difficult to get good IATs on dyno as they don't have enough airflow. Better to run some

FATS or something similar with enough air to have reasonable IATs.

My name is Bruce and I am an S4aholic. It has been 2 months since my last mod, lol!
