thank you.
Do you think that only one muffler is ok?
where you bought your hooker muffler?

Have them all running on a twin system ( Ford F250/ Capri 3,5 V8 SC/ Capri 3.0RS X-pack).
Got my mufflers directly from Summitracing

thank you one more time
what do you think about this muffler http://www.summitracing.com/parts/HOK-21508HKR/ ?

I suppose it depends on what you're after

I fitted this system to my Range Rover

Double S Stainless Sports System, not that noisy, but unmistakably V8

thank you all.
Fantastic your exhaust system!! Where you bought exhaust manifolds?

I´m divided between: http://cgi.ebay.co.uk/ws/eBayISAPI.dll? ... RL:GB:1123

and this

maybe second one is better.

Sounds even better if you drop the centre box out and just use the resonator.
