Flowmaster American Thunder cat Back
Flowmaster American Thunder cat Back
Hi, I' m new on this board. I live in the Netherlands where it's hard (and expensive) to get performance parts for american cars.
I own a' 88 bright blue metallic Camaro convertible with the 305 TBI-engine.
I'm thinking of ordering the 3 inch Flowmaster American Thunder cat back system. Has anybody got pics and/or sound files of this system?
I'm gonna loose the cat also since it's not mandatory over here on an '88 car. The Camaro is all stock except for a K&N air cleaner, a 160 degrees thermostat and a hypertech fanswitch.

If you want something that is gonna be quite loud and throaty, flowmaster is what ya want. I got a sound clip in my sig, but it was recorded with a $10 mic so it kinda sounds like crap.
I am 100% pleased with mine.

You get what you pay for
Thanks for your reply's. Am I right that the american thunder is the loudest and throatiest Flowmaster at idle and low rpm's? I live in the busiest part of holland, so I mainly cruises, not much chance to WOT with so much police. So I want a lot of sound at low revs.

I got the flowmaster Am. Thunders on my 92 z28 and they are wicked. I've never heard an exhaust this mean. Its cool when you get on it, people just turn their heads in amazment. I like hearing the deep tone it makes, hey I can set off cars alarms with it. The kit is awesome and if you want performance I would deffinetly recommend it. It alone shaved 3 tenths of a second on my quarter time.
It is absolutely worth the purchase!

I have the american thunder cat back. The only wierd thing with mine is, it has a 80 series muffler with 3' in 2.5' out. And ive only seen the american thunder with 3' in 3' out. But im positive its the 3' american thunder catback (Have receipt from last owner)
And I dunno if my cats gutted or not. When I knock on the bottom of it, it echo's. So im not sure if its gutted or not.
