Nothing was said about "Which flows better." To say that switching to a dual exhaust isn't going to quiet the system down, or is only go to "marginally" quiet it down is not true. The split in the system, the extra piping and extra muffler are going to absorb a good deal of the sound.

If he has a single and is currently so loud that he has to drop noise levels at the track, adding an obstruction of some sorts is basically the only way to do that, and my opinion is dual is better.

A single exhaust is like having different wheels on one side. It throws off the visual balance of the car and makes something just not look right.

 

wow, can it be, my first post in the FC section? after clocking over 250,000 miles on my T2 i guess i will give myself permission.

of course there's aethetics... and as i like to day, we can't all be divorced from the same woman.

so putting that aside, there's weight and flow. the duals are heavy. i had a RB dual setup and the mufflers are filled w stainless steel shaving to combat the higher rotary EGTs and the setup is heavy. probably not a major issue. while on the dual subject i would like to put in a good word for the quality of the RB dual system.

then there's the more important factor, flow. it is probably more complicated than just looking at the total area of the i d of the pipes. mufflers enter in etc and i am not currently well versed in the details.

i do think that if you have at minimum a 3 inch i d on your total exhaust system you are generally fine. i run a 3 inch exhaust on my FD and made 514 sae last month and the engine was very happy at 8600.

i can see it either way.

i still miss a number of aspects of my T2

howard c is really slumming it now posting in the 2nd gen section, lol

 

Single baby!!!

 

duals ftw

 

Big ol duals!!

 

I wanna go back to duals

 

Single here and love it, duals look good also, but i dont have a N1 style muffler so it looks decent. I mostly like the single because of the ease to drop it, 2 flange bolts and a hanger bolt and the whole system is dropped on mine. Less gaskets, less exhaust leaks.

That. And that.

 

Single looks cool.

 

had duals on 3 of my fcs

all i can say is that duals are HEAVY!

go with single they might be slightly louder but you can noticeably tell the difference in weight.

 

duals are for ppl who are OCD and vain enough feel like they need symmetry...

be a man, be logical, be single

 

It is a little more than one muffler and half a Y pipe of weight difference. This could only be considered heavy if: you are a 7 year old girl, your car has 100hp, or you are a racing professionally (which many people on this forum seem to think they are doing or will be doing).

Like this guys car (Sorry, I forgot your name), would not look nearly as good with single.

 

bingo!

 

My RevII is indeed very heavy, But I'd definitely regret sacrificing the sound for a lighter exhaust.
And if you're running canister n1 style mufflers, dual or single, its gonna be loud regardless.

On another note... It took ~40 posts till somebody posted a photo? How did that happen?
