Final Exhaust group buy
Posted: Mon Apr 15, 2002 2:20 pm
I am not an expert or anything but if we could reduce some to the curves that follow the factory exhaust, wouldn't it be more beneficial to increase in horsepower?
I want an exhaust done that will give me maximum hp gain; with total EVERY DAY drivability... I also don't want to drown out my cool Boxer engine sounds. (especially since I removed the snorkus).
>From what I understood on previous posts in this forum is that we want the extra heat before the turbo so a smaller header would be a greater gain then the four inch downpipe correct?
P.S. I am here to make my car faster not just SOUND faster. Lets hear from some of the pros on this one and possibly comments and suggestions on previous exhaust setups and configurations.

decide on how they want their exhaust built. Those who are still
interested, please send your prefrences to either me, the list, or
Russ at Subspeed, so that we can work out one system. I also just
recived this from Russ,
The plan is to build pipes in sections that very closely resemble the
factory pieces, though done with larger pipe. There will still be a
downpipe, 'B' pipe (centre pipe), and muffler section. Any of these
will be
available on an individual basis. As different configurations are
available
they will fit together in a systematic way. This way you can have
both
a
'B' pipe with and without converter for those SCCA weekends. Likewise
with
the muffler; glasspack for the hill climb - reversing style for the
commute.
I just need to know which style will be in most demand straight away
so
I
can get oriented to those details.

-So, please let me know what you think. There were more details on
the seperate kinds of exhaust systems that are available, but I will
post again here for convenience sake,...
I have a couple variations in mind for
the downpipe: 1) using a dump style turbo outlet flange similar to
the downpipe I make for the EA82T leading into a three inch pipe that
follows the factory routing; 2) using a dual tube design that routes
the gasses from the turbine into a four(?) inch pipe
that nearly follows the factory routing (reducing back to three
inches near the bottom) and using a smaller tube to route wastegate
gasses that follows the main tube in a parallel path that joins in
with the main tube about 24 inches down from the turbo. The advantage
to this option is that it offers the most flow. It is also the most
difficult to build (and expensive) due
to the fact that there would be two tubes and the turbo flange area
would have to be partitioned so that there would be no cross
contamination of gasses in the turbine housing. There would be the
option of including a converter in the first option but I don't see
any practical way of offering a converter with the second option.
The rest of the system would consist of three inch tubing that
follows the factory routing all the way back.
-So again, all who are interested (or not) please give some input.
Please say what type you are interested in, and your name and such.
The sooner we tell Russ what we want, the sooner he can build it for
us! Regards,
