OK, anyone here who want's to see what the OEM exhaust really looks like inside??

...I guessed so... :D
Well, I have this de-cat scrap exhaust and I was slightly bored today, so I got my angle grinder and ooops...: |
nice... next time you get bored would you mind doing the same with the transmission? I want to see how it looks inside too...
|
Thanks for posting this. Not much in there but it does quiet the sound, a little too much.
|
Thanx for posting these. So when one does the hole-in-the-stock-exhaust-pipe mod for achieving a better, throatier sound, does it retard acceleration? How do aftermarket exhausts for the 996TT add HP? I'm not looking for the scientific answer. I'm just vaguely curious.
THanx. |
Interesting, thanks for the pics... amazing how quiet these cars are....

THanx. Also in OEM exhaust there's two dense cats ( 400 cpi or more ) each side, and that "Pack-Man" style opening from the aft one is not very big... I really do not know how for example RUF ( or PBK ) has done their mod, but after opening this one I'd say that the Pack-Men are gone and those partially closed pipe ends are opened. |
Thanks for posting these pics. What is the steel-wool looking stuff? Any idea what it's function is?

THanx. Generally if an aftermarket exhaust truly adds HP it does so by allowing the engine to flow more air. The engine is an air pump and the amount of power it can generate depends upon how much air it can pump in a given amount of time. This requires of course that the stock system be overly restrictive to begin with and that other areas of the engine, the intake system mainly, does not then become the limiting factor. IOWs, a freer flowing exhaust ain't going to help much if the engine can't bring in more air through its intake system. Sincerely, Macster. |
Turbo motors benefit from as little backpressure as possible... the stock exhaust trades higher backpressure for lower decibels. Aftermarket exhausts do the opposite, for greater responsiveness/spool and output.
The intake side of a well-engineered forced induction motor configuration rarely is a limiting factor, IMHO. At least, no where near as much as the exhaust side. |

Cool. From the J of the TJW mod, this is cool stuff. You should post the photos in the 6so thread for completeness sake. I could if you allow me to do so. Jeff |

Can't help you with the hole in the exhaust pipe mod question. (Part of me believes this 'mod' is favored by those owners who can't figure out a way to attach cards to their car so as to slap against the spokes of the wheels.)...
Sincerely, Macster. |
Thanks a lot! Great information....
