Hi Guys,
as usual Eugenio is correct. For clarity, this is the engine installation on a RF 5 b with muffler and side exhaust:
and as you can see, there´s not room for a RF 5 muffler behind the engine installation on RF 4 SE-XST:
You can also see that the outer stubs or exhaust pipes are slotted and mounted with a clamp. The diameter of the outer pipe is 31 mm on SE-XST, I guess a "peashooter" will have to fit over a 28 mm pipe or something similar.
Bob Hoover has this comment on "peashooters" in his excellent VW-blog:
"Wanna go-fast/make-noise? Pull your peashooters and install a zoom-toobe. Most of the restriction in the stock system is in the peashooters, the big canister is just an expansion chamber. Get rid of the peashooters and you'll have about the same reduction in back pressure as you get from installing an 'extractor' on only two of your cylinders... but without upsetting the volumetric balance or causing the heat riser to clot shut."
So maybe "peashooters" would steal some power- not something you want in the RF 4.
By the way- I have two cracks in the stubs on the 4, so I will have to change them or have some welding done. In the "Maintenance"- "exhaust cracks"- thread there are a couple of more pics for more details.
