ANY Comments on a SPort muffler vs.OEM, Bursch

wacky73t · 02-02-2002, 11:06 AM

Ok heres an easy one , I as just wondering because I have not tried the sport muffler yet. I have used the stock single outlet and a bursch, that is supposed to add a little performance but it seems like it actually slows it down. has any body noticed a difference with the sport muffler vs. either the stock or the bursch (not sure which one but the actual tip looks like it belongs on a datsun b210. that can't be good.

The sport muff I had, had a nasty resonance at about 2500-3500 rpms....I sold it and got a Danske. Sold by out hosts Peluican Parts, the list is 799, but I got a real nice deal. Bursch has a rust problem right out of the box, and is built by handicapped crack heads...

The Danske is stainless steel and looks nice, comes in dual and single out. The dual is louder, but passes the 92 dbA level and San Diego DE and AX events....probably too loud for Laguna though.....

I have not heard a bad porsche, so I really wanted to find out about performance differences, not tone. I'd put somthing on that sounded like grampas fart if it made it perform a little better.
what about the performance?

Just put a Bursh Carrera on my 83 SC. Seems fine to me. Not too loud, just deeper. Seemed to perk it up a bit. (I also gutted the cat) Fit and finish was very good. I guess those handicapped crackheads are becoming pretty good welders.

Maybe they are getting better welders, but that was the knock on Bursch for a long time....the ones I used in the past, the paint burnt off after 100 miles and then they started to "oxidize".....

As to performance....most fuel injected motors like some back pressure, but any free flow muffler will improve performance. In my experience, you lose a bit of low end but gain midrange and top end power.

come on........... I know your out there lemme know your input or does everyone have a bursch?

Thanks fo the help richard, this is almost like looking for drivers on the net and seeing posts like "oooh i need one too", "that happened to me too", "I have the same problem".
no offence, but am I supposed to take the reccomendation or research ?
I really was looking for info on the sport muffler not the quality or opinions of bursch (as I already have one) or danske, which- the website is either nonexistant or in danish- which is of no use to me either.
comparisons -comparisons......
oh congrat's on your new danske ...is it better than a sport muffler? ( my original question) let me know if you have any noticable performance improvement ! "Really," that was the question.
thanks, and no offense....really!

0 to 60 in 8.5.......... 95 to 55 in 2.2 oh yeah!

dickster · 02-03-2002, 12:23 AM

none taken (wise ass)!!

i'm doing some research cause its all so bloody confusing!!

i haven't got mine yet. i am in the same boat as you. i want to spend my money on stuff thats gonna improve performance. i emailed a few tuners to get their opinions etc.

andial are pretty respected (very) so i'll go with the danske. i could post the email if you like, but i can't until tommorrow (its at work).

hope it helps.

Here is a pic of the stainless Dansk 2 in 1 out after a year of use. As far as performance, The SSI's make more of a difference. I think after that, it is mostly sound produced. The Dansk if very quiet, (almost too quiet). I have been told they get louder with use.

It's kind of hard to nail any perfomance linked to just the muffler....unless you slap a muff on with known hp ratings as a benchmark and then do a dyno run. I don't have a dyno sitting in my garage....

Seat of the pants....I backdated my heat exchangers on my euro SC to SSIs....I tried out the Borla (LOUD), B&B (almost as loud and buzzy), oem sport muffler (Loud and toothache resonance), the Danske (quietest of the four)......they ALL performed equally well, to me....not dyno numbers.

But I have to be able to convince the wife to ride with me, AND it's a cab, AND I have neighbors.....the Danske nailed it.....as to Fabiani....did not try it....but the price tag convinced me that it was not for me.

Just my $.02

YMMV

richardnelson,

hi (yes I can be a wise ass) but not to be offensive, I just get bored at home...,anyway, yes it is confusing,and you get alot of opinions trying to not go thru the experience that others may have already done. and try not to spend too muc h time and money experimenting.
I guess the thing to do is go to a goo club meeting and start talking to people and asking probing questions.??
I dunno. I was either just going to put the stock muff on or convert it to a sport muffler.
But a quick note about the opinions. maybe it as already answered by "mikez" in previous post.
in that you cant nail any perf on any of them which means to me you cant really feel a difference, I don't need a dyno to tell me if my car is performing any better. If I can't feel the difference I just save my money for somthing else performance related- I know there isn't much very cheap and effective. maybe ingnition sys or somthing.

campbellcj · 02-03-2002, 11:29 AM

Here's a pic of a Bursch (happens to be a 914 flavor, but extremely similar) after about a year of low-miles, low-rain California use.

And IMHO it sounded like crap and did nothing for power too. I gave it away for free and put an OE sausage muffler on that car; never regretted it...

Jim T · 02-03-2002, 11:53 AM

Don't know about performance differences,

but from a quality difference,

the OEM muffler is a stainless steel beauty. It looks and fits right, and can last for 25+ years. (Mine is 23 years old, has had one paint job and looks like new)

The Bursch is about as cheap and low quality as a muffler can get. Cheap mild steel. Horrible paint. Really cheap internals that blow out pretty quickly. The pipes are as cheap as you can use and still get away with it, as is the muffler.

But, on the other hand, you can buy them for cheap. So, they are not a ripoff, you just get what you pay for.

I've had Bursch on several cars (mostly 914s). I would not sully a street 911 with a Bursch.

They may not be bad for a track car, as I'd imagine they are lighter.

Jim T · 02-03-2002, 11:55 AM

Yeah, Campbell's pic pretty much sums up Bursch, in my experience.

Unless they have made some major improvements in the past few years.

pwd72s · 02-03-2002, 11:59 AM

You didn't say if your 911T was an MFI or CIS model. If you still have MFI, I'd strongly suggest staying stock. There was a string about this on the S registry some time ago. Strange as it sounds, MFI cars can develop flat spots in power delivery if the exhaust is too free flowing. You actually can decrease performance with an aftermarket muffler on MFI cars!

"I really like my GHL! All stainless, with great quality and sound. You get what you pay for."

(Mmmm....just look at those tits!)

Heres a link to a Fabiani mp3:

Fabiani Sound Bite

The little bit of rattle is from an overdriven mike in my laptop

wacky73t · 11:22 AM

Thanks for the input guys-
tha Fabiani soundbite sounds really healthy- definitly cool.
as far as the bursch, well, i think I have decided to put it where it belongs... on someone elses car. I have CIS mot MFI, I don't know how much back pressure it needs but porsche must have designed the stock for it to run well with it.
so I am gonna go stock and try it against the crappy bursh( which was free) so you are probably right you get what you pay for.
though I won't be spending 2k on any muffler unless it comes with a lifetime supply of blowjobs!

how about the sport muffler? do I need the extra flow?
