Exhaust question

[mhjo]

I have a complex setup on my exhaust, partly because I enjoy a quite ride and that I would like to explore the power of the engine.

My setup is as follows:

Hedmann shorty headers
H-pipe
2 x Dynomax turbo mufflers
1 x Dynomax transverse muffler

This setup works fine, but I suspect the 2 in - 2 out transverse muffler stealing HP.

My question is:
If I replace the transverse muffler with two resonators, will this give more HP gain and and still keep the exhaust pretty silent?

- Or are there other options?


(yes, I want it both ways....)

No.

What you have is a modern version of the factory 67-69 system, except the factory system had a pair of glasspack-style resonators under the rear seats, and a pair of low-restriction 180° mufflers in a single transverse case.
