Custom Exhaust

[John V]

I'm sorry - regardless of exhaust system - if somebody ever tells you they have a Boxster that sounds like a Ferrari, instruct them to locate said "Ferrari" which bears the same sound and have them demonstrate. Ain't gonna happen.

A flat-6 can have its own distinctive wail (ever hear a 996 GT3 with straightpipes at redline? Amazing) but it sounds nothing like any Ferrari.

/rant.

i dunno man, i get annoyed over the sound of a ferrari after a while. But don't get me wrong, i love the car. I like the Lamborghini Gallardo sound too

There's no way you're gonna get rid of that drone. But...to keep the exhaust and muffle the sound in the cabin, you can....

....just wear EARPLUGS when you drive. At least you'll sound cool to others around you.

You're not going to solve the drone. Sorry. It's just not going to happen.

I heard of someone putting header wrap around their mufflers and they said it helped the drone by about half. Might as well give it a shot.

or maybe you could try this "super sonic acoustical mat"




"This high quality mat offers superior sound dampening control to reduce road noise, rattles, engine noise, and any other noises that are bothersome. The high density polyethylene film with an aluminum foil composite is abrasion and tear resistant. The gray film provides structural integrity & strength, allowing the material to bend, move, & return to shape even under tension forces. The product is 70 mil in thickness, contains a high temperature adhesive backing, and is easy to trim & fit. The rubberized compound is applied with the high temperature adhesive to absorb all those out of control noises."

I hate to tell you, but it will likely get worse. It takes a little while to break-in your muffler - it will get louder over the next month.

Just go with straight pipes...

This is a exhaust setup with the bypass pipes, have the guy who built that custom setup for you do this and change the tips to what you like.

My favorite video with current setup.
This is me approaching from about 1.5 to 2 miles away.
You can hear the car at full throttle in the distance but i had to back off...i was hiting going way to fast for public roads.

There are a few other videos with the new set up in different situations.

By the way right now the car has stock cats, aftermarket headers, muffler and a supercharger. There is another phase of mods that are more agressive than what i have now.

Have a great day,

Gary, I don't doubt that the straight pipe set up sounds loud, but this guy specifically is looking to tone down the resonance/drone in his car, as it is driving him crazy. I doubt a straight pipe set up would help tone down the drone, no?

[spine911]

Magnaflows or most american brand mufflers=drone issue, plain and simple. Only way to turn it down is with Resonators(definitely wont work in most porsches bec. of the limited space) or replacing your mufflers.
IMO, the more highend european made mufflers are your best bet when you dont want the interior drone issue. I have a BRABUS exhaust with Resonator deleted in my MB E55 and there is absolutely NO drone even with the resonator delete mod.

The straight pipes where so LOUD i did not hear any drone, or my, cell phone, myself thinking....

The straight pipes where tounge in cheek, the other two options where realistic options.

The current setup i have has no drone, its actully to quiet for my taste and i may be looking for a used GHL.

The setup with the bypass pipes sounded GREAT but my tips where not the most attractive.

BTW Boxtaboy..i did get you wink. I love sarcasm.

Have a great day
