I don't want to re-post what's been discussed a million times before, but I need an answer from someone who has actually compared all three following exhausts:
Greddy SE GoTuning Dual 70mm, T1R 70R EM Dual, and the Invidia Q300
If you have heard/ridden in any 2 of these exhausts in person, please give me your feedback. My first priority is for the exhaust not to drone too much. There are a lot of posts that say "this exhaust is quiet" and "this is too noisy", but it's all relative and i want to know how they compare
Thanks

 

I have the T1R 70R EM Dual . and I love it so far. when i cruse i don't get the drone. but if im giving it a little gas the drone is a good amount. and at WOT it sounds deep and aggressive. no ricer sound. and it does not sound like i have a couple loose rocks in my exhaust .
if u cruse ur fine but if ur gassing it , u will hear it

 

The Greddy SE has unequal length piping after the Y, which makes drone worse. The Q300 and T1R Sparrow have less drone, especially if you combine with with a properly sized test pipe. However, you can reduce drone even further by replacing the front section of the exhaust with one of my mid-pipes (in my signature).

 

everyones perception will be different. you should just find someone local and hear it for yourself to get a real good example

 

this...
I bought the greddy elite 70 single since everyone said it was pretty quiet and minimal drone. Man IMO, this thing drones like a MOFO. All depends on what your definition of drone/quiet is. GL!

 

I totally agree. But where I live there are only a handful of S2000's in the whole country, none of which has any of these exhausts on.
I just want to know how they compare. Before the S, I had an EP3 CTR with a K24/20 Frankenstein swap, I/RH/E, cams, the works, and that thing was LOUD. I could feel the exhaust slowly taking the cabin apart. I want a 70mm dual exhaust, and a very important factor, and I know from experience how much drone sucks.

 

Greddy SE dual drones pretty bad. Got rid of mine after 2 weeks. Tried the 70rem single and it's comparible to the Greddy I believe. If I were to choose between the two I'd probably go with the 70rem.

No ASM 70 single? That's the only 70 I've heard with no drone.

 

I like the Q300 the best out of all the ones you've listed. Im currently running an ASM 70mm single and love it. Sounds super mean at WOT and is very quiet when you want it to be. I got over the whole look of single vs dual pretty fast. I think the single looks super aggressive and can't beat the weight savings as well

 

The look is why I would prefer a dual to be honest. I've looked into the ASM's, and I've read that some people have had their resonators rattle over time, which would require cutting and welding the exhaust over again, something I would not enjoy doing.

With that said, the ASM dual I.S design looks amazing, given that it has nothing in its construction that would wear over time. But I don't think it's reasonable to pay 4k for an exhaust. The Q300 is also half the price of the 2 others. How does its quality compare?

Ive had a T1R 70RT so I can speak for T1Rs quality which I think is top notch, the welds were super clean and the fitment was great.

However, drone and T1R go together hand in hand...

Have no personal experience with the SE dual but to be honest, I dont like the look of it much nor do I like the exhaust note.

The Q300 is made by a cheaper brand but the look of fthe burnt titanium exhaust tips is quite nice. Build quality wise I would probably do a quick search as those aren't as subjective as exhaust note and drone
