senator exhaust

[cali]

Hi all,I've been toying with the idea of putting twin pipes on the senator to get more of a growl out of the 5l but it alresdy has a single 3" from the y pipe,no resonators an two mufflers at the back.Should I go with the twin pipe system or just play around with the mufflers eg getting rid of one muffler or putting some different ones on.

the single 3in without rear reso already would have more 'growl' than a twin system,

have you got headers and hiflo cats yet?

Yep got the standard hsv headers but no cats(I'm assuming you mean catalytic converters)I hate them and two mufflers at the back.
