FS: Factory style DIY Sport muffler kit
 

I got the first batch (3 sets) of sport muffler tubes finished and ready to ship. These pieces are mandrel bent and made from 0.060 wall one inch stainless tube. Due to lower than expected costs I have reduced the price to $100 (includes shipping CONUS). I have the first two sets sold, and strong interest in another two sets. This kit is designed for home conversion to the factory style Sport muffler. You will be required to do your own final fitting, cutting and welding. You will need at least two 1" bi-metal hole saws (Lenox are the best I found), a strong drill, a carbide die grinder, and a welder. I use a mig welder with standard .030 wire). Figure 3-5 hours labor. PM or call me if you are interested.

I can also convert your muffler for additional cost.

These tubes only fit the Boxster S muffler to 2004. I can also make the tubes for a standard Boxster muffler (they are slightly different).http://986forum.com/forums/uploads01...1365264861.jpg

sent you a pm

Replied. :-)

All three sets are sold. I'll make some more if anybody is interested.

After a few requests I have made a few more sets, ready to ship.

Could you tell me about the end result? How much louder, any drone, etc?

No drone, and the loud depends on how much throttle you are using. At idle its not much, if any louder than stock. Going down the street normally its not enough to gets a cops attention or wake the neighbors. But if you "get on it" you, and everybody else will know it. If you want I can do a phone call so you can hear it. This might give you an idea of the sound. PCA autocross Retama 19oct13run1 avi - YouTube

Sounds pretty good. Not obnoxiously loud at all.

Do you send drawings/photos/instructions/templates or anything like that? Is that price good for Canada too?

Probably have to charge you a little more for shipping. The first car I did is now in Canada. Don't really have instructions, but I can provide some guidance. Since these are hand made every one is a tad different and each one has to be custom fit. The hard part is cutting the holes. Stainless steel is very hard to cut. You will probably need at least two hole saws and good cutting oil. Its about 3-5 hrs work total.

This really is the best solution IMO for great sound. Just more "attitude" when you open it up and not a hint of drone. Good job!

:cheers:

Thanks. :)

Pm sent, please let me know. Thanks

I think I'll do this, but I'll have to get back to you early in the new year. This would be for a '99 base, btw.

New year bump

What mig wire are you using ? Does welding SS need special wire/gas ? I have a mig but never welded stainless.

You can use a regular mig. I do. There is a process for SS which requires special gas and wire, but for this its not absolutely necessary. Its just that your welds won't be totaly stainless, but they will be about half stainless. Its really pretty easy to weld.

Id just weld them the old school way, with an acetylene torch and some old metal coat hangers:cheers:

Are you making any more of these?

Any performance gains?

As needed. I have a couple sets to sell right now. Then if there is more demand I will make more.

None to speak of. Its pretty hard to improve on stock these days.

How's the sound cruising on the highway at 70 mph or so ?

Its a little louder than stock, unless you step on the throttle. Then it gets proportionately louder. Its not obnoxious though and there is no drone. Have you check out my video?

Yes I did but in that situation there is a lot of on/off throttle vs cruising that's why I asked. I will probably be purchasing from you but I have to actually get my car first ! :D Obviously you are doing this mod with the muffler removed from the car. Are there any potential fitment/clearance issues when doing this mod outside of the car ? Do you recommend tack the two tubes in place then loosely install the muffler to make sure everything is straight with no clearance issues ?

The first set I made had fitment problem so I changed the design a little. WHen you install them just make sure you tuck then as close to the muffler as possible. Taking the muffler off is only a five minute job. Getting the bumper off is probably harder. You dont need to tack the parts in place. Just mark where the holes go. Then you will need trim the the pipes to fit. You will end up taking about an inch off each end.

Monthly Bump

PM sent on the pipes.

James I sent payment on 3/21 did you receive ? I want to make sure payment isn't lost. Please advise. Thanks

I'm at the track but I had not received it by the time I left.

james

Well that makes me nervous, please check when you get back from the track. Will that be tomorrow ? Thanks

Been a while so time for a bump.

Still have a couple available.

Way over due for a bump.

How much would it be for a non-S set?
Thanks.

Price is the same.

Only two sets left.
