1.9AAZ + straight pipe... TOO LOUD!

in my experience the empty cat acts like a resonating chamber, and give the exhaust an objectionable note, it creates turbulence that causes it to be heard in the car a lot more and the tailpipe sounds like it's babbling. I'd dump the cat altogether.
Contact me for hard to find for idi and tdi parts

Flowmasters flow bad for non-turbo engines and are just plain restrictions for turbo engines.

The best mufflers are absorption types that flow straight through. They muffle well and do not restrict flow.

I was tempted by the straight-through glasspacks, but I've heard that they don't do much for resonance... which was a big issue in my case.

The Cherry Bomb "Turbo" is a good compromise. Sounds good.

The car is a 96 1.9TD with a K24, running on vegetable oil.

Now it's all the random rattling buzzing and wind sound that I have I am trying to eliminate.


Ha! You should hear my Samurai turbo-diesel. It's the only vehicle I've ever owned who's top speed is determined by wind noise.

So who'd posting behind thw GreaseCar name? Is it Justin? I would love to get down there someday to see your facilities.

This is what the cherrybomb sounds like, it's quieter in the car.
