Ha.. Im an expert on it. I've listened to them on YouTube. [emoji12] [emoji12] [emoji12]

My brother in law will do it for me no problem when the time comes. First I gotta do the water pump as the car is off the road.

Hey Particle, you have any clips of the car because I was really thinking about doing this mod but want to hear what it sounds like? Startup, idle and standing still rev up to about 3k then 4K would be good please?

I'm interested in a set for a 98' the previous owner did the crios mod. Do you think this will still work even with the drilled holes?

I probably wouldnt do that. It would spoil the effect. What really makes this modification great is the sound you get. Any other mods will likely screw that up.

Due to increased overhead and shipping costs there will be a price increase to $120 effective 1 Jan 2018. Orders placed till the end of the year will still get the old pricing.

Thank you for your business,
james

TIme for a bump

New production run available.

Still available. Tag this post if you PM me because I dont get email notification of PMs.

What is your current price on these ?

$120 shipped.

Do you currently have a set for the S muffler ? My last attempt to pay you by check was vetoed by the USPS , what is your PayPal address ? I want to see how the beast will sound with this mod .

Yes, my last set is for a boxster S.

PM for paypal/email address.

PM sent . Thanks

Thanks. Will be shipped tomorrow.

If you have a tracking number please provide it. I am in the stick's and packages sometimes take a while to get here . Thanks

Any chance of getting the tracking number ? Thanks

Box arrived yesterday . Nice heavy wall pipes . Thanks

I am looking forward to trying this modification . I have had a Dansk bannana muffler . a GHL , and currently running a Mille Miglia . I guess as I am getting older I want more of a stealth muffler . Jake Raby has told me many times it's hard to beat stock for power . Been proven on his chassis Dyno many times .

After I do the mod I will schedule some time on his Dyno . At that time also going to load some new tunes via their new in house tuning . We made 278 rear wheel HP with the current muffler and tuning software . Hoping to get closer to 290 or so .

It will be interesting to see the results!

j911brick last night I positioned the pipes by eye to see how they fit . This is on a S muffler . To get the pipes roughly in the center of the exhaust tips the pipes that will go into the inlet pipes is about 3/4 of the ways on the inlet pipe and a 1/4 of the ways into the weld of the inlet pipes . Does that sound about right ? So the hole saw has to cut through some of the weld of the inlet pipes to the muffler case ? Any chance you have a pic or two of where the pipes go into the inlets ? Thanks

I have same question... I'm glad rfuerst911sc brought it up.

I also have a set of these from j911brick I have been planning to install (S version). When I test fit them the seemed really tight (or close) to the weld seam on the main muffler. I was assuming they would plumb in perpendicular to the inlet and outlet tubes, but maybe not.

j911brick, I trust you figured out the best fit - please confirm. Thanks.

Email has been sent . Thanks

Didn't get it.

Hmm your email is j911brick@comcast.net correct ? I saw your PM will call you tonight . Thanks

I just resent an email , I went back and checked and I had a typo . Still planning on calling you tonight . Thanks

James I called the number you sent me via PM , it rang several times then I received a message stating it was unavailable . So if you can post a few pics here on the forum it will help me and others . Specifically I want to see how/where they enter the inlet pipes. Thanks

Today I decided to attempt this modification . I bought two Milwaukee 1 " bi-metal hole saws turns out I was able to do it by just using one . First thing I did was eyeball where the pipes should be on the exhaust tips . I outlined with a Sharpie and made sure the alignment was good at the inlets .

I also made Sharpie marks on the lip/flange above the exhaust tips so I could notch them . I wanted the pipes as tight to the muffler as I could get them . Once it was notched I again checked the alignment and made some adjustments . I then took a spring loaded center punch and made my indentations on the tips . Drilling the holes wasn't too bad I used some 3 in 1 oil as cutting fluid .

Did the same thing at the inlets . I had to do some grinding and filing to get the pipes the way I liked them . I ended up cutting off about 1 " off the pipes on the exhaust tips ends and about 1 1/4 " of the inlet side . They are tight to the muffler can as I could get them . I tacked them in place as I ran out of time . I hope to take a few pics tomorrow .

Sent you a pm

Update pics of welded bypass pipes
 

Sorry guys I'm way late posting my progress , between 2 weeks vacation and other projects taking priority it fell behind . Anyway the pipes are now welded in place . I did the hole drilling and tacked them in place at home with my mig welder . I could have finished the welding myself but decided to have a friend that can tig weld complete the welding . I think I did a good job of getting them centered on the tips and have kept the pipes as tight to the muffler body as possible , time will tell if I have any fitment issues .

Not sure when I am going to install it as I have a lot of DIY projects burning at the moment . Even though I am retired time is still a precious commodity :D While the muffler is on the bench I'm going to clean up and polish the exhaust tips as it is much easier out in the open . I will update my thoughts about the sound and dyno results once I get there . In the mean time I hope my pics can help others doing this modification . :cheers:

Man where does the time go ? :D Today I removed the Mille Miglia muffler and installed my modified S muffler . The S muffler at 34 lbs. is 10 lbs. heavier than the MM , not happy about that but it is what it is . I will try and get an audio clip at some point but I was surprised how much growl she has when you get on it ! The added pipes/muffler fit perfect with no clearance issues at all , the pipes are tucked up behind the rear valance with plenty of air space/clearance . There is zero resonance ......... nothing ...... NADA :)

I took her for a 30 minute drive and I came to the conclusion I really like it . It is quiet when you want to be by going easy on the go pedal , or you can floor it and unleash the angry hornets nest :D Time will tell but I may have a MM and a GHL muffler for sale in the future . :cheers:

Hoping to get on Jake's dyno this month but his shop is swamped so we'll see .

Finally had a chance to get on the dyno and do some tuning . The last time on the dyno ( 4 years ago ) with a GHL muffler we made 277 hp I don't remember the torque . It has been 4 years and 7,000 miles later so not exactly comparing apples to apples . But with the stock muffler with the bypass pipes we made 282.22 hp and 252 ft. lbs. torque at the wheels ! Not bad for a stock muffler but I know there is probably a little more power in the exhaust . But it pulls like a freight train so no complaints on power . However with my combo of engine mods and exhaust it is WAY TOO LOUD when on throttle . For cars that are not modified and have cat converters I'm sure it is great but for me too loud . It will be coming off .
