Ok I just found out from my supplier that Apexi is no longer making the RS exhaust I have on order. To make up for it I've been offered the Mugen twin loop for a reasonable price of $1700 (~US$970).
This is an "Australian" supplier so please dont tell me I'm being ripped off (I already know I am!), or that I can get it cheaper at <insert name> Racing in Kentucky or something (because shipping will kill me).
Unfortunately I do not have the luxury of time to look through 100+ exhaust posts.
I've already spent a **** load on a crap sounding exhaust and $1700 is a lot to pay - I do NOT want to get it wrong this time.
I'd like to ask several very specific questions about the exhaust ... please answer them if you can.

I'm primarily after a quiet exhaust that does not drone or intrude into the cabin too much ... I've been burnt before!! I know that it does not flow as well as an N1 or spoon or whatever but I have minimal mods and my cars primarily used for daily driving.

Most importantly what does it sound like?
Does it have a puttery or airy sound?
Does it drone inside the cabin?
Will it give me headache after 10 mins of driving?
Is it quiet enough to hear the intake?
Does it fit well (or am I likely to need it modified to fit)?

Thanks to anyone that can help ... and thanks to anyway to anyone that cant.

Mike

 

From what I've heard, the Mugen exhaust is very quiet. That's kind of the purpose of the twin loops. Somebody please correct me if I'm wrong. I doubt it will drone inside the cabin or start giving you headaches.

 

I have the older internal twin loop and a freind of mine has the twin loop (external) on his ITR, they are loud on acceleration, but at cruising speed they are barely noticeable. by loud i do not mean boomy, its a real deep noise and IMO very pleasurable to the ear, i can clearly hear my intake at WOT in lower gears, you are not being ripped off on that price, thats roughly what i paid for my cat back system about 18months ago. When you hear it you can tell that its not a cheap custom/knock off exhaust. If you drive easy/accelerate easy then the exhaust noise is a low deep sound..you will not be disappointed. My friends exhaust is a little quieter than mine but he's only had it a month ot two, so it will possibly get a little louder as it get older...let us know what you think when you get it fitted.

 

mugen exhaust is the best sounding exhaust on the market. very good flow characteristics as well. price is not a rip off its normal.
