Quietest 3in exhaust

[xr4x4ti]

This is the opposite of what most people want, but who makes the quietest 3in can back exhaust for a 2017 GT?

Thanks,
Tim

Check out Solo Performance. They are known for Stealth and Quiet kits. Not sure what they offer for the GT, but I'm sure they can give you some guidance.

For a 15-17 car, the AWE Touring is pretty tame, as is the FP by Borla Touring. I think Borla also makes a Touring system (not under the FP banner). Those three would be the most tame that I can think of. I think MiamiGT350 is right that Solo Performance also has a pretty tame system.

You can always buy an exhaust and add more mufflers to it, it will be a pain

this is what i'd like to do eventually

The Borla touring system has a resonator that keeps the volume down. It’s smaller than the giant suitcase that’s stock but still keeps it quiet

Quiet and 3" don't coexist because there is such a limited market. I've tried. Active exhaust is your best hope. I even added some magnaflow resonators to my 3" active kit and it was only a marginal improvement.

H pipe, stainlessbros resonator, corsa touring mufflers is surprisingly quiet up to about 2300 rpm during normal driving, possibly quieter than stock, plus has the bonus of being full 3” straight-through for all components. It’s too bad the stainlessbros is flimsy and fails. Will be replacing the sb and h pipe with a Jones equivalent soon but I don’t think it will be as quiet due to less perforations. The Jones is a better fit, though, due to the dimensions and built in x pipe.

Have you considered fitting 2 of the longer 3" SB bottle resonators side by side in place of the SB dual/dual resonator ?
It is too bad the dual/dual isn't more robust. Thin wall 300 series welded without a back purge and oxidized welds are destined to fail sooner than later.

AWE Touring paired with GESI Gen 2 UHP catalytic converters will give you the exhaust flow to support upwards of 1,000 hp while still remaining relatively tame when you have your foot out of it. It will still be loud at WOT, but will sound clean and deep with minimal raspiness.

Varex valved system is super quiet with the valves closed, but you cant go WOT with the valves closed due to too much backpressure (atleast when you are boosted) and its insanely loud with the valves open without cats.

Thanks for all of the great feedback!

A buddy of mine has the borla touring catback with borla's resonator, Pretty quiet system but a lot more free flowing than the stock exhaust

i just installed a true full 3” 304 Stainless system from AFE in California. I had never heard of them , but did some research and they had good reviews. I installed it myself, the fit and finish are very good. This has a great Deep sound with no Drone. I’m running Stainless Power Headers with High Flow Cats.

+1 for varex
