FS FS: Thermal 3” exhaust
- Thread starter Ldstang50
- Start date
My wife hated my thermal 2.5 after I put SPD down pipes on. Just too loud for around town driving. She didn’t mind it before the down pipes with just the thermal. Got to the point she hated trading cars when I worked on hers.
I put a couple Vibrant resonators and it brought it down to the pre down pipe loudness.

These. You could also fit the larger canister type vibrant if you wanted it a little more quite than these. They took the higher annoying frequencies from the DPs away but kept the other goodness imo.
Vibrant Performance 1792 Bottle... https://www.amazon.com/dp/B000E3VHVO?ref=ppx_pop_mob_ap_share
One side about 5” from the down pipe. Other side slid into the front side of the Thermal dual resonator. The vibrant were a great slip fit. I put 4slits in the end of the vibrants with a cut-off wheel and clamped half on the slits and half off. Come spring I may weld them if I like them. Totally sturdy with no leaks now though so I may never get around to it.
The black pipe is a DP, I had them ceramic coated for heat rejection.

Very little difference down low. When I would just normally accelerate like half pedal, it would start to get annoying above 2000-2500 with higher frequencies, like ricer-ish sound if that makes sense. Sounded like I was racing with normal driving. What I love about the Thermal is a lot of the sound is lower frequencies. It doesn’t sound like your typical V6. The DPs seemed to bring that annoying v6 sound into play. Still sounds awesome at WOT

I dont have downpipes but the vibrant ultra quiet resonators really toned it down, knocked the raspy buzzy bee sound down around 2k-3k rpm when normal slow driving thru the gears. And now it doesnt sound like im trying race people everytime i take off from a light. Its still loud but it did help take a few decibels off the top. Pretty mellow comparatively. Does it sound good? Still a v6 but it doesnt sound like a Honda anymore which is good.

Hey man, I’m just seeing this. I apologize for taking so long to get back
She said it was too loud. There is a drone and some rasp. I put tge stock exhaust back on, then put on Gibson mufflers. No drone, nor rasp. It’s a bit louder than stock, bit quieter than the Thermal
Per my phone’s db meter, the Gibson is about 5dba quieter at 70mph vs the Thermal
