Exhaust swap from HSE to SC

You're pretty familiar with this situation, in fact the HSE would probably achieve a reduction in performance or sound by fitting a RRSC system onto the N/A HSE ?
The design of the RRSC exhaust system was tuned for the Rootes blower on top, which is why it differs from the HSE version - but there's a lot of math involved !
There is nothing stopping you from swapping them over, 'knock yourself out' and go whole hog though be warned of consequences in performance & exhaust flow.

Vin, I think they are only talking about fitting the muffler portion of the exhaust on. As the post states it's simply for the tail pipes to stick out. However, a free flowing exhaust typically would not effect the performance. The only time you could possibly loose performance is if you eliminate back pressure. There could be spots on a dyno that you see decreases as well as increases depending on how the flow of the exhaust gasses escape. I highly doubt that by just changing the back section you would loose any performance.
You could to be quite honest, where the HSE exits and tucks up under the car the SC exits and bends down and out. it's a simple steel pipe with a stainless steel brushed aluminum looking cover at the end.Bruin2006 said:

I read the title, not the detail and sometimes with my previous aftermarket exhaust work on the Dyno we achieved a reduction in performance on a Honda V-tec !
My mate just fitted mid-pipes to his Nissan Skyline R35 GTR to replace the originals, made more drowning noises with no improvement so went back to the OEM's.
I remember removing a front pod on a Barina back to an original airbox & interior noise was deafening, since back pressures were affected by the barrel muffler ?

I checked with the local dealer and the parts guy told me that they don't sell just the tips alone...you would have to buy the whole muffler. So for now, I had a local muffler shop weld some stainless tips onto mine that look pretty close to the supercharged ones.Bruin2006 said:
Thanks Duke.
Reminds me of the Overfinch FFRR tested by the "Topgear" TV show from old blighty earlier this decade ? Boy - 'Jezza' absolutely pushed that mansion on wheels !
The Overfinch model appeared to have replaced a rear muffler with twin oval outlets to take into account the additional thrust from the autobahn storming 5.0ltr.
