Sorry, but there is a free lunch when you do the engineering work and I copy your work when the IP expires. Cut a few corners to reduce cost and get it close enough for government work (GM).

The technical term is reverse engineering, nobody plays by the rules anymore.

I too am looking at different options to install. Are you saying this muffler/exhaust system has zero engineering? If so, why do you think this is so?

I just installed the headers, mid-pipe and muffler from delubozparts on my '00 Boxster S.

The install:

I bought the "factory second" headers with one O2 bung in the wrong place. Since I have only one set of working O2 sensors I thought this would be no big deal. I had a lift and removing the old exhaust was easy, it had been off the car 6 months go. The headers would not bolt up without massaging the holes in the header flange. After some minor grinding, the headers bolted up. The O2 bung on the driver's side was OK but the wire needed to be extended. The header flange is too close to the brace and occasionally hits it lightly. This happens when slowing down or sometimes at idle. The passenger O2 sensor tilts down more than I would like, but I don't think it will hang up on anything. It needed the wire extended as well. The mid-pipes fit fine. The mount for the exhaust needed some massaging of the mount so that it was not binding. About 4 hours to install with a full shop at hand.

Impressions:

The sound is amazing, sounds like a GT2 RS. I got no drone at any rpm. On the highway, the wind noise is still louder than the exhaust. But when I put my foot into it, the sound puts a huge smile on my face! I'm no kid, 55 and gray Driving like I usually do around town (short shifting below 3000 rpm) would not attract any undue attention. 80 mph is about 3000 rpm and no problem hearing the radio over the wind noise with the top and windows up. Windows and top down, you won't hear the exhaust unless you wind it above 4000.

Conclusion:

For the money, you can not beat this exhaust. The shop that did the work was so impressed with the value. They could not believe what I paid for the whole exhaust. They said they will be ordering some for their cars. They were paying, for headers, twice what I did for the whole exhaust. The minor fitting issues were worth the savings.

Final Thoughts:

I wanted to do a dyno run before the headers went on, but the dyno shop next door opened late today so the headers went on without benefit of the baseline run. I will be doing a run before I install Pedro's TechnoTorque II. The only real complaint is the clearance between the header flange and the brace which rattles sometimes. I will clearance that when we do the TTII.

How much was it all together? (Minus the shop labor)

IIRC it was $500 plus or minus a couple of bucks.

Great Reviews, Thank you maj75 :-)

[Jaxonalden]

delubozparts,

I have a question about the pipes I received. The extra little pipe, how do I clamp that on? Is there a clamp I reuse or do I have to go buy one? Beautiful pipes by the way, love the flanges.

Hi Brad, will all due respect to the resources and nrg you guys have put into designing what appears to be the ultimate product, there are some other packages that makes it worthwhile to go with. I got myself the NHP Motorsport exhaust system and in all honesty, there is no drone (as advertised). Okay perhaps quieter than the other aftermarket basement-made exhausts, for 2k it gave my car an incredible weight reduction, some minor HP gains, GT style tailpipes, plug & play installation (2hrs) etc.... that beast starts to reveals itself past the 4k rpm and sounds like a beauty in the upper rpms. I personally give it a 9.9 on 10.

Just not as cheap as some others but check it out!

I'm not an engineer (never played one on tv either ) but shouldn't there be a way to wrap something or lengthen something or shorten something or open up or close down something just a little to change the exhaust frequency to lose the drone?

I don't know why someone wouldn't simply avoid the RPM range where the drone exists. I can't think of a time when I knowingly drive below 3,000 rpm.

Obviously you didn't try it in real life scenario.... you have to get your RPM above the 3K and sometimes its not that quick - also driving behind someone, getting to the intersection, or just getting up to speed in the traffic will bring you enough driving below 3K...
Not to mention simple inconvenience, to remember to avoid 2-3 K RPM.

I have the NHP V1 on mine, I like it but it is actually a little quiet for my taste, I am hoping a set of test-pipes will open up the sound some

Are these still available?

I was Che's guinea pig many years ago with his sport manifold and twin chamber muffler. The set on my 2.5 increased HP and torque with dyno pulls before, during, and after the various parts of the install.

However, that drone of which so many have commented is actually deafening when it's raining or too stinking hot for the top to be down. My ears actually throb when I get out of the car.

However, most of the time I'm tracking my car now, and with a helmet on, the wail of the intake and exhaust combo is glorious and I don't need to look down at the tach at any speed to know if I need to upshift or if I can safely downshift.

I wish Che would make those straight pipes with two bung holes on each one so I could use them on my 2.5 (for track use only, of course!).

[heliguy]

Che, are you still offering the muffler at the member price of $275?

[Homeboy981]

Time for me to "ring in" on the Cat Back and Bypass pipes I got from Top Speed.

They are an excellent combo!

I am budget-minded and these pipes deliver AWESOME SOUND at a great, almost unbeatable, price point!

We introduced John and Top Speed to the North Texas Boxster Enthusiasts (or maybe the other way around) and he sold out of these quickly! Sorry guys! Now that he has them back in stock they are a MUST BUY if you were even thinking about upgrading.

I DID notice better sound AFTER they were broken in around a tank of gas later but you will be driving with the top down and the stereo OFF to hear that exciting exhaust note!

BTW, did I mention they also add a few horses too!

Have had mine installed and am LOVING THEM!

Thanks to John and all the people at Top Speed Performance for hosting the NTBE meeting there! We will see you soon, on the road or at the track. You will KNOW it's us by the sound, it is LUSCIOUS! Did I mention they shaved 20 lbs. of "boat anchor" and add more horsepower! It's a no-brainer!

What else do you have John? I'm thinking about headers, GT3 seats, or an intake? Hmmm
Boxster on people!

Still Valid

[BruceH]

I'll chime in as well. I HAD a drone at first like others have mentioned. I wasn't happy. I continued to drive it to "break" it in but tried to figure out what was going on. I also have the bypass pipes and the included clamps with the pipes were not sealing very well. Started a search and ended up with some clamps that both seal the joint but also add some mass. The result, no drone Much happier now!








The rear is now lighter and breathes much easier without the secondary cats!

33 pounds lighter according to my scale. That includes the pipes and muffler.

The sound is the real benefit though.

For those looking, John (che) has a used one on eBay:

Hope you don't mind me posting this John.
