Re: HPX system for the BA XR8s
So did I. They are adamant that 2.5 inch is too big for the XR8s.
THeir system keeps the orignal Y piece (which is 2.5inch)...same as the herrod setup.
They run a dual 2 1/4 the rest of the way. Herrod's is dual 2.5 going into a single 3". I have no doubt both these setups have been designed to maintain back pressure.
As you probably know I have tried a dozen setups. Previously they have all been barky. However as of yesterday I found a muffler that is giving me the deep and boomy sound I was after. The current setup is a 2 1/2 inch running to a front twin in twin out muffler. Then 2 1/4 the rest of the way going into a smaller resonator.
Now that I have the deep and boomy sound, I am missing the v8 pulse!! You can only hear the pulse on idle or if you floor it. The rest of the time it runs like a turbo 6. Creates a very similar sound to the herrod setup except louder.
What I want to do is get rid of the merge pipe at the front and have 2 seperate pipes. This SHOULD give more pulse. But I'm not sure how this will affect performance (if at all). Perhaps someone with some knowledge on balance pipes can enlighten us?
