Project 46: from the 101 Projects for your Porsche Boxster book

I just upgraded my stock exhaust to one I got off of eBay for $250. I just wanted a little more noise out of the car, nothing obnoxious. But I thought the stock exhaust made the Boxster almost sound like an electric car! I put together another detailed how-to video as I went along. Hopefully it helps a few of you out! As usual, I didn’t find anything near as detailed as this video out there already.

A big job. You did well for not having done something like this before. I learned a lot from watching and will start mine soon. Thanks!

charles ward says:

Exhaust paste to make it seal up properly?
Good video tho 🙂

time traveler are we there yet says:

good job
but i would rather just cut them off and run strait pipes
thats just to much to get the same result

Andrew Gibbs says:

Jerez, why don't you edit or speed up sections of your video. Gave up after watching you mess about taking the rear upper spoiler section off. Sorry

Graham Essen says:

You could save yourself a ton of pain by buying some new exhaust clamps and some suitable fasteners. Jeez man at least use a hacksaw to shorten the bolts for the hanger bracket.

Rui Martins says:

Got it! Nice idle but in rotation sounds like a trawler. Disappointed.

Bob Rose says:

Hiya great videos. One little tip. On the exhaust clamps. When you were tapping them with the metal bar and hammer. You seemed to be hitting them on the outside where the bolt is. You really need to try to hit them in between so you prying them open .. sorry don't mean to teach you to suck eggs.. I'm Bob from the uk. I'm work for Cosworth as an engine builder. And I'm a mad Porsche nut. Having had seven over the years. I started with 924, then 924s then a few 944s them my baby a 911sc which I restored from the ground up. Engine rebuild by me and I re sprayed her as well. I now have a cayenne. As you can tell I love porsche. Keep up the good work my friend. I love watching any thing to do with these beautiful cars. Kind regards Bob…

Do you experience any drone on the highway? Also could you update the link for the exhaust you got? Appreciate your videos man!

TexSquirrel says:

Thanks for showing the "mistakes." The learning process you go through help us a LOT! The "not necessary" or "this didn't work, so I did this" stuff is priceless!
Most internet DIYers pre-loosen bolts. I can tell you're not doing that. I can see the dirt being released…and the actual struggle to get stuff loose.

Speedwelltuning says:

Urgh you Americans are unlucky, those registration plate lights look awful!

Harold Callahan says:

Great Video Aaron!

Chris Moseley says:

Hi, I have just done this to my 986, the twin pipes on mine seem a lot closer to the heat shield and the bumper. I cant see how I can adjust the exhaust to be any lower. Any ideas or is it a case of just pulling on the welded bars you think? your video has been a big help, but like Robert below, I had to angle grid a number of the bolts on the cats…. oh and I swore a lot more as I did this project. thanks!

David Janzen says:

Doing this install today, I didn't take the old one off – do the u-shaped pipes slide into or over the mid pipe/muffler or just but up against them?

M B says:

A big amount of work, but removing spoiler and bumper isn’t required. You can remove from under the car by simply removing the bracket bolted to the back of the transmission (3 bolts), and with pipe clamps loosened, and cat brackets unbolted, the whole assembly will come out. Much easier!

Robert Hooles says:

Amazing weight difference between the old and new exhaust systems. My original back box weighed 17kg, the new one weighed just 7kg
