Sorry, but no! Tomei ELH is not going to sound dramatically different than XXX brand on stock catback.

Why don't you record a clip and let us here this quieter sound you speak of.

Why the exclamations points every time you reply to me? I'm not here to try to win an argument, I'm just telling my experiences, no need to get so excited.

And the Tomei is different than the aFe header because that is a 4-2-1 design with its own uppipe vs. a 4-1 design which I used with the stock uppipe, so I would expect them to sound at least somewhat different. I never said it would be dramatically different, I just said mine is quieter than stock now (and that's not by much). It mainly reduced the low frequency sounds, which are the most noticeable.

If I had any kind of decent camera, I'd make a clip for you. You're comparing a different header and downpipe setup, so it's not exactly an apples to apples comparison. They're similar, but not the same. You don't have to believe me if you don't want to.

for max quiet with a downpipe: ELH, and stock catback. The headers mellow the exhaust because of the equal pulses, and the stock catback does a decent job of decreasing sound. At least on my GR hatch it did.

Use your phone to take a video. You have increased the airflow with bigger piping, and yes maybe some of the lower frequencies are gone, but the overall sound is much louder. In fact, I hated the way it sounded on a OEM catback. Way too tinny around 3k.

GR hatch is a different exhaust (catback and muffler setup) so really hard to compare.

I actually believe the big muffler on the hatches do a lot better job than the dual mufflers.

I have the Fujisubo Legalis R catback with cobb catted downpipe on my 09 sti hatch, it is very close to stock. I wonder how this exhaust is on the 2015+ STI

I wasn't lying when I said I didn't have a decent camera, I have a LG Octane phone from 2011. I think I might be the only mechanical engineer in this country without a smartphone.

I know the car was louder than stock when I just had the DP, but I noticed right away that the ELH made it quieter, especially at idle. You have to remember that you're comparing headers and downpipes with somewhat different shapes and diameters and those things produce slightly different sounds.

There's gotta be a video with a 4 into 1 ELH, Grimmspeed catted DP, stock uppipe and catback somewhere out there for you to hear.

TheLegend,

I am interested in the Madad Whisper but their website
says "Note: We have not tested on a 2015 model yet but anticipate a few minor changes are needed. We will announce official 2015 fitment soon.".


I emailed them a few weeks ago but got no reply.


Do you have information that it fits the 15+ STI?

Dave

Don't wait on maddad that posting for 2015 testing has been up for ages, I prev had maddad and it was perfect for me and OP I'm actually tempted to buy the Gd axleback from maddad and have a custom setup welded up.
