Exhaust help

A 2332 is not going to sound like an original speedster (with a 1500 or 1600)-- it's a 50% bigger engine. It needs to breathe, and to breathe it needs an extractor-type 4-into-1 exhaust.

It's 100% possible to quiet a sidewinder down with a different muffler arrangement than Tiger sells as stock with the A1 sidewinder, but it would be a fabricated, custom exhaust from the collector onward. I've built no less than 4 different arrangements-- by far the sweetest sounding was one that wrapped around the front of the engine and had a muffler beside each valve-cover. It weighed about 50 lbs and cost about $500 to build, doing it myself with mufflers, mandrel bends, and parts from Summit Racing. It took most of a month of nights and weekends to get right.

I'd recommend getting what Greg recommends. The car will run better, and you can buy ear-plugs if you don't like it.

Thank you for the advice.

Have Greg aim the exit ti straight back. Aiming it straight back makes it loud for anyone behind you. Aiming it down makes it louder for you. Not a lot but it helps......Bruce

You’ve made the jump to a 2332...don’t stop now.  The A1 is the way to go.

I agree with @aircooled : exhaust out the back is the way to go.  Although I advocate about a 45 degree angle as straight back may get some resonance if it sits high and flows out directly onto a fiberglass body panel.  Not only does it keep it relatively quiet inside the car, but it also helps keep the dust down when you are on a non paved surface.

Wait!! What?!! We only drive on paved roads Ed. What are you talking about?

Dude, you're driving an AIR-COOLED car. The amount of air blown through the engine for cooling will stir up way more dust than just the little tailpipe.

My Spyder engine bay does stay cleaner now with the sled tins, so the spent cooling air goes rearward instead of down to the ground, stirring up dust.

I remember pulling in to Deals Gap with my speedster, parking in the gravel parking lot then watching John Hallstrand pulling in behind us with his SAS Cabriolet.  While he was water cooled, the two radiator fans at the rear blew down onto the ground and as he pulled in there was this big cloud of dust around the rear of the car.

Not Ed's car. His turbo-charged beast of an engine and previous viaduct for a tailpipe sitting a few inches off the ground pretty much blew clean the road behind him. Made it cleaner for the guy behind but there was a constant chance of getting a rock in your windshield which is why I never follow anyway. I always lead and never follow. Lol

half of you engine noise comes from the intake.  If you are really worried about noise do some research on how Porsche quieted down the 912.  I made some custom intake hats that have cone air filters.  The amount of noise they killed is unbelievable.  The second picture is a set of 912 intakes.

Intake noise I like. I had a  built 3.2 short stroke 911 with triple Webber 48’s what a wonderful sound

I have FCR carburetors with UNI pod filters on my Ducati. When I whack the throttle it sounds like a hurricane.

Intake noise is great, until it isn't. It's not too loud with the top down, but 107 dB at full throttle is a bit much with the top up. And it's in the 90s under cruise. Without the top it's not a problem at all.

I put CB aluminum turbo hats over the carbs with pod type air filters and it really took the edge off the noise. I can't remember the exact numbers. Shorter velocity stacks need to be used, the turbo hats are shorter than regular air filters.

Things got quieter with an Air Head Air Cleaner on a Suby...........Bruce
