Developed to give you the high performance you want without sacrificing the interior sound level comfort you enjoy. The SpinTech Truck/RV 8000 Muffler makes great SOUND under acceleration, yet at highway speeds you hardly hear it! Works extremely well on all BIG BLOCKS and V-10s!
High Quality Built muffler. Nice sound! Just a little louder than my stock! 100% Satisfied!

8000 truck RV muffler

I haven’t installed the mufflers yet. I have bought spintech products in the past. They have always worked fantastic and sound amazing. The customer service is outstanding! Great group of people to work with! Spintech is the way to go!

i like it

i had this installed on a 98 chevy k3500 with the 7.4L engine. cab and chassis truck with a flatbed. at first i had the shop put a turn down after the muffler, that was way too loud. i had them install the factory tailpipe and am much happier with a full tailpipe. there is a rumble/growl but not too loud. i really like the sound.

Great sound when you want it, silence when you don't.

These mufflers are great for performance street applications when you want a nice aggressive sound when you're on the gas, and stealth mode when you're off it. No drone while cruising either.

8000 Truck/RV Muffler Series
Posted by Trevor on May 12th 2022
Purchased this for my wife's Armada, to replace the rusted out stock exhaust. This exhaust is perfect if you want a little rumble that's not going to annoy your significant other, or your kids who are riding in the back seats. Sounds great, doesn't really bark until your really hammering down the throttle. Definitely recommend and will be putting this exact model on my K1500 Suburban.

Great Quality

Muffler arrived in good shape packaged well. Produced exactly as ordered. Installed by a custom exhaust technician with new matching piping. The sound is perfect for my tow vehicle application and I feel as though the power delivery is improved. This muffler is much more quiet than I expected, but I’ve decided that’s a good thing.
Would highly recommend for RV or towing truck application.

Quality muffler, should be sufficient at making my project stealth. Will find out once project is complete.

I have used a few different series over the years, and I just put this one on a 408 LS Silverado with a large turbo and the tone is perfect.

8000 series muffler
Posted by Josh LaFreniere on Nov 11th 2021
Quick delivery and the muffler's build quality is as good as I remember. I had a pair on my truck 20 years ago and loved them.
This 8000 series is the perfect replacement for the 40 series F.... that was previously on my 04 Tahoe. It now has a low smooth rumble at idle and during normal driving, and awakens like a beast under hard acceleration.
