Eliminated the mufflers on the boxster S

[harryrcb]

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.

Great video Harry. I'm envious - the closest I'll ever get to driving Sebring is Forza 3

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?

I did this mod last week and I thought I would give the results. I had the local muffler shop remove my stock muffler and make the new pipes. He used 2.25 dia. pipe. My cost was 160.00 total. I left the shop and it was a bit loud. Also there was an irritating drone from about 2K to 3.5K. I was expecting this but had never experienced it. I ordered some baffles from the net and installed them. They were cheap, about 15.00 shipped, they bolt in. They were 2" x 8" and worked nicely. I had to get the muffler shop to weld a spacer on the end for a nice tight fit, $5.00. The baffles seemed to eliminate some of the drone. I also ordered some heat proof fiberglass wrap from the net, 15.00 shipped, but did not like the result. I am presently using just the plain baffle, no wrap. I had it out last night and it is coming along. I might try using a small amount of wrap just to see about the results. I do think the baffles will allow me to get it inspected for the street. My main reason for the mod was to loose the weight more than make it louder. I haven't weighed the muffler yet but I would think I lost about 30 lbs. I might get chrome tips, they are on the net for $25.00, but I haven't finished tinkering with the setup yet. Total cost about $200.00. If anyone wants any pics I will try to accomodate, just send me your email address. Bill, Pgh, Pa. 99 Box.

Its astonishing to see how some members take a "bubblegum and chicken wire" approach
to modifying (or should I say destroying) their exhaust . In view of the fact that Porsche spent considerable time designing their system, by the same token it requires a methodical approach to changing or modifying it . The irony in most of these cases is, that not only has power probably been lost, but engine reliability has likely been compromised as well.
