Quietest 2.5" axleback or midpipe+axleback for my JDL UEL? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

stockysnail · 04-29-2014, 08:10 PM

I'm looking for something quieter than my existing setup. It sounds great but is getting a little old daily driving at the volume it's at going up any kind of hill.

Here's what I have.
Header: JDL UEL
Overpipe/Downpipe: Nameless performance 2.5" with high flow cat and helmholz resonator
Midpipe: Stock
Axleback: Nameless performance offset 2.5" with 5" mufflers

All the axlebacks I'm seeing that are on the quieter side aren't quite 2.5" (i.e. Invidia Q300). I'm supercharged and would like to have 2.5" all the way back. I have someone that I can get a resonated 2.5" Works midpipe from but still need a 2.5" axleback, or just a mid+axleback solution, but 2.5".

Anyone have ideas? I'd prefer something the opposite of rice if possible. If no 2.5" quiet axlebacks exist I guess I'll have a decision to make.

This guy has the same header & front pipe, with a Perrin 2.5" catback exhaust. The Perrin is a nice & quiet exhaust.

It is. That, and the Greddy SP Elite.

Those are basically the 2 choices for quieter exhausts as opposed to loud (the rest of them).

Edit: Okay, and the Perrin 2.5" resonated. The 3" Perrin is one of the raspy loud ones.

I have a Ti tipped Q300 theyre pretty quiet...been tryig to sell it locally actually

Magnaflow is quiet as well, with a nice deep tone.

Got video? And is it with front pipe & headers?

On phone I am. Therefore, if mistakes I make, Frank Oz blame you should.

I didn't make a video. I also have the Nameless over/front pipe combo with high flow cat, but no header. Even with the front pipe, it was very mellow sounding. I think the Magnaflow would be a good combo for someone with a header who doesn't want something loud.

Could I possibly get a video of your current setup? I was thinking about the same, but there is no videos out there. Thanks!

I read that the Q300 was about 2.345", not a full 2.5"

I've installed a few Perrin 2.5" and 3" exhausts on cars with stock headers. They sounded about the same as my Nameless 2.5 offset 5" when I had the stock headers. I can't imagine it being much quieter if any with the JDL UEL.

HKS legamax Premium is one of the quietest, have to get used to the 5" tip though

Model (Engine): Scion FR-S(FA20)
Model Year: 2012
Main Material: SUS304 Stainless Steel
Tip Diameter: 124mm
Main Pipe Diameter: 60.5mm to 54mm
Noise Level: 88/89dB (Idle: 56 dB)

Forget about it. Any way you cut it, the moment you add a header to these cars they get crazy loud. I have been on a few setups now and they are all loud. Hate to say it but 4 bangers just don't sound very good when you open them up. Drone everywhere. These aren't pushrod 8's with a loopy cam profile. That sounds good at any volume.
