Glasspack Deep Performance Tone Inlet 2.5 Pipe Connection Outlet 2.5 Pipe

I recently installed the Thrush Glasspack Deep Performance Tone muffler with 2.5” inlet and outlet, and I couldn’t be happier with the results. The sound is exactly what I was looking for—deep, aggressive, and clean without being overly loud or obnoxious. It really gives the exhaust a classic performance tone that stands out without droning on the highway. The build quality feels solid, and installation was straightforward with the standard 2.5” connections. Once installed, it immediately improved the overall character of the vehicle—both in sound and feel. For the price point, it’s hard to beat the value you’re getting. If you’re looking for a simple upgrade that delivers a noticeable, satisfying exhaust note, this glasspack is a great choice.

These don't sound half bad, good and loud. My 77 C10 still sounds kinda like a old farm tractor at idle but they wake up when you put your foot into it. I changed my exhaust from a Y pipe single exhaust to a X pipe dual exhaust.

Installed on a 04 Chevy 5.3 Silverado with high flow cats. Performance is great and sounds awesome. Not to loud and flows good. Single exhaust with tailpipe. Good quiet ideling around. Deep performance sound when accelerating.

This glaspack is great i used it to replace my muffle and cat in my hooptie it sounds good and has a nice tone to it after a day the red paint started burning off which is fine because my car is blue but you can’t see it anyway

Heat started flaking and peeling the paint of the ends but sounds great on my 2010 fusion sport

Great product

Sounds great and easy to install, replaced a broken resonator with this.

THIS IS A TOP QUALITY CONSTRUCTED MUFFLER, SOUNDS FNTASTIC, THE LONGER THE MUFFLER THE BETTER THE SOUND !!

To loud!! Dont buy

Excelente

these mufflers fit nicely in my 4" side pipes, and gave the car a deep tone and was quite a bit quieter that what I had. nice product

Easy to install and i like the sound when shifting down and stomping on the throttle. Thought it would be louder though. I do only have a V6....

Esperaba un sonido mucho más exagerado cerca a traer tubería directa pero son bastante callados, al acelerar es cuando realmente suenan, en relenti el sonido es bastante callado y suena hasta stock están genial para escuchar música cómodamente pero que ruja cuando lo aceleras UPDATE: Corté la tubería hasta donde termina el resonador (previamente tenia tubería hasta atrás del carro) es un sonido bastante bajo siento yo para ser un glass pack pero curiosamente si hay bastante drone o ruido dentro de la cabina como el que habría con un mofle o resonador mucho mas ruidoso, igualmente diría que esta bien por el precio pero si buscas algo ruidoso, este no es el indicado, es un glass pack cómodo para un auto del diario solamente, ni tanto ruido ni poco
