I was wondering if anyone has ever done a dual system on an FB. If so does anbody have pics. Also has anyone ever done dual center exhaust on an fb, like the vipers have(not necessarily the same tips though). Cause I got my rb headers and was thinking about doing something different with the ehaust route. Maybe even side exhaust , either under the doors or out a hole in the fender (if you seen the Top secret i think it was a supra, has the blow off eject air out through a hole cut in fender)

I don't know, prolly won't have the cahs though , but what are your opinions

 

Tried it as an experiment using twin 2'' pipe as the fc. The result was disappointing, not worth the extra cost and weight.

The problem with all minor changes is the difficulty in measuring the outcome. Practically everything is subjective as the impact is so small as not to bbe measured either at the dyno or et. The limiting factor on exhaust/muffler systems is whether it's legal and that varies widely by state.

So the answer to your question depends where you live, being in California that is really limiting.
