Ok guys and girls, quick question. which exhaust is going to give the best of both performance and street quietness. i was looking at either the fatboy or dual quiet pack or whatever its called. its for a 1916cc so its gonna need to flow more than one for a stock engine but has to be fairly quiet. and which would look better. i was thinking the fatboy is nice looking but a goiod set of tips on the dual quiet would look nice as well. any ideas??

im always fond of the tuck away with the muffler parallel to the guard to allow ease of access for the valves

will it restrict the engine breathing at all? im not very experienced with exhausts. and is it quiet? im looking for quiet when im driving normal but won't restrict the engine at max rpm.

it shouldnt restrict it and it will be quiet. i ran one on my t4 and at 3500 rpm it was 90db so just under legal but barely noticeable once in the car

3500, i don't think ill be sitting on that rpm for long unless im going on the 100 zone, so that sounds good, would the dual quiet be quieter and does anyone know if they have a wierd sound due to the twin exits for a 4 cylinder?? and is the phat boy much louder than the hide away? i guess the sound from the hide away is up under the guard as well so it wouldn't be as bad.

VW Trends magazine did a good test comparrison.
Not all exhausts but a few. Gizes you an idea what to look for
Additionally fully merged gives better performance over semi - but semi fits better.
Dual is quieter at the expense of performance.

They are all semi merged in the VWTrends article. Have a look at the systems Penrose is selling. They are fully merged

i should mention that it was a 1 7/8th inch system from the extractors which were a modified genie set to fit the t4. ill find a pick.
not the one i was looking for but very similar
heres the one i was talking about

ok thanks for all the help so far. so where can i get a fully merged hide away exhaust system from in aus? and what brand is the best to get and will it fit if i am going to run an oil pump cover style oil filter?

apart from one of the vw store the only other place i can recommend is rapid exhaust as they make their own systems.
