The one thing my car will never have

[mechtech2]

One fear is to open up the exhaust for more power and better sound, and then find a resonance at whatever speed in the interior which is really annoying!

I wonder if a 4 cyl split 2 X 2 would give a good sound in a car.
Maybe a small crossover. Motorcycles had systems like this from the factory and aftermarket. But they generally were smaller engines and higher revving. The sound could be good.

I had a 2.0 4 cyl in a Mazda truck (B2000). Sounded great. It was manual, so when in neutral, the truck barely made a sound. Soon as you drove it or got on it, the sound was fantastic.

Of course, I removed all of the EGR related pipes off the intake, had replaced the stock manifold, pre-canister, cat, pipe, and muffler. I replaced it with a flowmaster 50 series delta, high flow cat, a header and 2.5" pipe.

Keep in mind this was on a 1986 vehicle that didn't have to pass emissions. I'd never do it on another car - hence my earlier post was to save the dough and do something good with it.

Most don't sound great, but I've heard a couple that I like. My buddy had an '89 Corolla SR5 coupe with a 1.6L that had a good bark to it. He just went one size bigger tubing from the header back, with no cat and a Cherry Bomb Turbo muffler. I don't think he even had a resonator in there, but he may have. I also like the growl of my mother's 2.4L Quad Four Sunfire engine with the factory exhaust.

^ that's subjective....
I personally love the way the high reving 4cylinder honda motors sound. 6 cylinders generally sound better though..more mean.

A small V8 around 2.4 - 3.0 liters would be perfect for the car.


Yes, Mallett was one of the 'tuners' I was referring to in my post.

Who has a V-8 that small, save for some old Ferraris, and some select Brit cottage industry racing engine companies??

Nowadays? Don't know. Used to be quite few of them. Daimler had a 2.5 litre V8 that was only about 2.5 feet end to end when Jaguar bought them but they killed that engine (and the 4.5 liter variant) pretty fast in favor of their own I6.

Jaguar built the AJ V8 in displacements as small as 3.2 liter, but it is DOHC - i.e. physically very large, at least the AJ V8 in our XJ8 is.

A small pushrod V8 with modern engine controls in the Solstice would have been like a modern day AC Cobra.

Only better.

Then listen to a PT GT or an old Turbo Dodge. I have a 2.5 Shadow 3" exh and bigger turbo with 3" Swing valve, hi flo cat, and dynomax ultra flow. SOunds nice and deep burble , not rice can [censored] [censored] on Civic. Best part is when you lift at 20 PSI and give a nice BOV salute

JMO.

I like the sound of my turbo EcoTec just fine.
Could be more mean with an aftermarket cat-back, but I tend to be one who doesn't care to have my exhaust noise what tells people from half a mile away that I think my car is fast...
