Entill I have the money to get the parts and time to put together an exhaust for my 3800 series II s/c can I run the stock dual out single in exhaust I got from the Fiero store ? Anyone see any problems with it? Will it cause to much back pressure since its ment for such a smaller engine?
I would not run any exhaust system designed for a 2.8L on a 3800 SC engine. These systems are just too small and too restrictive for any supercharged 3800. Using too restrictive of an exhaust system on a 3800 SC engine can result in KR (detonation) problems among other things.
I would recommend nothing smaller than 2.5" diameter pipe using mandrel bends (single pipe systems) and low restriction mufflers and catalytic converters (if those are used). 3.0" mandrel bent tubing is the way to go if you want the best performance.
