Re: My 1986 Firebird
I haven't see very many silver ones ether, I like the color. I think it would look really good with the original Firebird wheels. If it's as solid as it looks, you got a good buy.

Re: My 1986 Firebird
Can't say i've heard it specifically, but I have yet to hear an exhaust other than stock that I like for the 2.8/3.1l motors. The only time it sounds good is at idle. Give it some gas and it doesn't sound good anymore.

Re: My 1986 Firebird
However, I'm not sure how well a rounded block is going to stop that car from freewheeling back. If the parking brake fails, and the car somehow jumps out of park, it may just roll over that thing.

With that kind of incline it doesn't hurt to have a little extra cheap insurance like a block behind the wheel.

Re: My 1986 Firebird
Looks like a clean car and love the wheels. Yeah the v6 cars do not sound good with aftermarket exhaust.
Re: My 1986 Firebird
and dynomax is the only exhaust that sound like the stock v6 sound, just a little bit higher on the gas

Re: My 1986 Firebird
Yeah the Dynomax turbo system is not loud at all on any engine. I hate turbo mufflers as they are not loud, but for a V6 when you don't want loud they are not bad.
