Re: remus universal, does it add power? or no? (blackGTI)
EC tested a Remus-specific muffler and it made 12whp on a chipped Jetta.
Not bad for a 2.25" muffler.
Get the right one and couple it to a TDi bypass and a DP. You will be pleased.
Add the above to a chip and intake, and I'm making 198/230 to the wheels. And I like Tyrolkid's post when someone was whining about 3"dp/cat and 2.25" piping beyond that...and how it sucked...then he says something like "Imagine, a setup like that only got me into the 13's..."
