Thermal 2.5" vs 3"?

[jwuonog]

Has anybody heard both in person? What are the differences in sound level, tone, drone?

here's my 2.5

That's the one I ordered this week. Any drone at all?

zero!

Haven’t heard the 3” in person, but just installed the 2.5” with CVF downpipes on mine and absolutely love it. Great sound, not too loud, and no drone.

Thanks. The downpipes may get added to my list.

Best part of the Thermal is how easy it is to install. I did mine today and once the old exhaust was off, it was maybe 45 minutes to put the thermal on with the ST on ramps. First car part I've ever installed without the use of curse words.

Thermal v. Borla S-Type: which is louder? I want something that sounds better than stock but is not too loud in the cab. Thx

Borla is louder.

Just got my ST back from the mechanic, 2.5 Thermal installed. The sound is just sexy as hell... Like others said no drone at any speed up to 120.

I have 3in w/stock down pipes and disabled FENG and it sounds perfect

Here’s a couple revs of my Thermal 2.5” with CVF downpipes. Going to work on getting some videos while driving to show how good it sounds.

here's my 2.5

I appreciate this. I ordered this solely because of this sound clip! Arrives next week. I have done research with it on stock downpipes (which Is 100% fine for me). I'm glad that their is no drone, I talked to Thermal R&D, and he mentioned that If you want to upgrade downpipes later, they recommend 3" but the reassured me if you "Step" on the accelerator you'll hear the exhaust! LOL. Pumped fr something that isn't the stock one.

I have the 2.5 with stock downpipes. Need to disable the FENG today so I can hear it without the fake noise. I really enjoy the cold starts. Also the staggered tips look amazing.

Since this came back up I figured I'd post another video that I took. CVF Downpipes to Thermal 2.5"

I hope mine goes that smoothly. Mine came in today!

What happens at 120??? Lol. Thinking of ordering 2.5 thermal as well. Was deciding between awe borla and thermal. Seems like thermal is the quietest which I like. I drive a lot for work and don't want loud exhaust at all.

I wonder if 3" a lot louder than 2.5". From the videos it's hard to tell but I do like the tone of 3" better. Any thoughts on that. I'm looking for something that will not get annoying on long drives.

The 3” is definitely louder by quite some margin, I thought the tone between them both were about the same. None will get annoying on long rode trips, at cruising speed they aren’t much louder then stock from what I heard. Around town the 3” will be mildly loud while the 2.5 will be pretty tame until you get on it. Personally, I’d choose the 2.5”, I like quieter exhausts on these cars.
