The system alone was worth close to 20 hp and 10 ft lbs.

Each time our project 335i gets a power adder mod, it's dyno. The results were between the two systems with all the mods on it?

Never mind your second post was all the clarification i needed.

So i guess my next questions are:
How much for the dual exhaust?
Is it a complete 100% bolt on "downpipe-back" exhaust (no 2nd cats)?
Do you have pictures of the system uninstalled (i'd like to see the piping overall shape and bends)?

For pricing you can PM or email us.

Here is the link from Borla if you are interested to know how the exhaust is routed:

Here is the original thread on the dual muffler system:

With the 2nd cat delete pipes, the whole system will be a bolt-on.
