Dual Exhaust

FM Former Member
I just got a new Beck Speedster and I had a dual tipped exhaust (non-high performance) installed. I think it is only a regular type muffler with two tailpipe outlets, not a real dual exhaust system. This is on a 1915cc Type I engine. The current exhaust tips just barely clear the body (the body under the bumper was modified for the twin tailpipes/ exhaust tips. I think the exhaust is a bit loud for small exhaut / tailpipes. Is there a way to make it quieter? Would longer exhaust tips (like on the older real Porsche 356's) help reduce the noise a bit? Any idea where to get the straight small diameter chrome exhaust tips to fit this engine/ car? Do they make silencer type exhaust tips that don't kill the performance?

Any comments would be appreciated.

Robert, if you have a 1915 your motor deserves better. Even if you're running a near stock cam (110) and stock heads you will notice the difference if you install a free flowing exhaust system.
VW Trends did a very good comparison of exhaust systems on a stock motor. You may find the results interesting.

Correct me if I'm wrong katz & jammerzzz, but isn't the sound aspect muffled by more resistance inside the muffler itself? I added a flared pipe extender to one of my exhaust systems, lenghtening that bad boy, and it got a little 'tonier'...certainly not quieter.

More stuff in the muffler means more back pressure which cuts down on engine performance.
