Thanks Tom , so my downpipe now starts off 5” right off the turbo for only 4” then I have it reduced down to 3.5” for about 4 feet to get under the car where it goes from 3.5” to dual 2.5” merge pipe all the way out the back . Was thinking about going from 5” off the turbo to a 4” for about 4’ to get under the car then go from 4” to a dual 3” merge pipe all the back..

You are welcome. Like I said 5" off the turbo for 10-12" is fine then reduce to the 4" downward to under the car, etc.
