hi
Any one fitted a sports exhaust to 911 carrera 1987
seen a couple of ararticles about replacing cross over pipe with straight through unit
to make it sound a little crisper ?

Iv offen thought abouts this i never quiet made my mind up so iv never got 1 to date yet.

Depends on how much you want to spend

Better heat exchangers are available as a complete system all the way through.

We tend to use items that are an improvement on the SSI design which is inspired by the early 911 design before emissions in California pushed them to use the design as seen on the SC, 3.2C and on models. (designed so that the primary silencer could be replaced with a cat for the US market)

BHP increases as well as a much improved sound result. Especially when combined with a chip designed to work with the system.

How much would a chip and set up cost ?

And what kind of power increase would you get ?
