Eliminated the mufflers on the boxster S

[jwade]

I am running completely catless with stuff in my sig below, but have oem PSE muffler with butterfly valves in the open position.

Car sounds amazing and when you hammer the throttle and get it in the 5000+rpm range!

A friend of mine heard me coming down the hill towards my neighborhood the other day and made the comment to me that it sounded like a race car... He owns an '89 911 coupe and is a porscheophile to the hilt.

I only took off the mufflers, as for the sound I will get on that asap, weather here in CA is not as sunny and beautiful as it use to be!

Would love to hear what this sounds like.. Maybe I'll have them take the mufflers out of my Borla.

It sounds like an F1 Ferrari, huh?
Glad you're happy with it, though.

I almost forgot, when I ran with Chin Motorsport in August, a friend of mine showed up with his 03 Boxster S with straight pipes. Is it loud? Well, yah!! if you want I have a utube vid following him for the warm up and first lap. I could only hear his exhaust, I have headers and no cats with a loud borla on mine, but his exhaust definately occupied my ears. lol Here is the link if you want to hear straight pipes

you can make it as cheap as you want or if you have the money buy the "brand" name products available, the cheap way - get on Ebay and purchase a set of headers for you car around 110 with shipping, go to your local muffler shop and have them duplicate your mid pipes (without the cats) and then fabricate the pipes to replace muffler to come out at the same location. I have a local shope bend up pipes, without the end plate for 50 so if you want them to weld those on they might charge you around a 100 and maybe another 100 for the muffler replacement. check with your local shops. the key is chop around.

Dude, you weren't kidding! Sounds great, but wow, drowns your car out big time.

I don't think the OP has straight pipes all the way like the guy in that video, he says he kept the cats, just eliminated the muffler. I'm sure it's still very loud, but if he has all four cats they will reduce the sound somewhat.
Usna, any progress on that sound clip?
