Stop by the local hot rod shop and look through a Borla stainless steel
muffler.
I ran a 3" in 1999 and a 4" last season. The three inch was more quiet but
the engine
builder says it cost a few, so we went with the 4". The 4" is so much

louder

that the radio is now useless. In the formula Mazda series, they run the
Borlas very close to the engines. They have about 160 HP and are rear
engined, so there is little room for the muffler. The Borla is just a tube
with about 1/16" holes and stainless packing around the outside. Take a

look.

It may give you some ideas.

Lynn,

  Do you have a part number? Borla makes a lot of different styles of
mufflers. Some are claimed to be light weight others make no claim for
weight at all but appear to be very heavy. Which are you using?
