Just wondering if anyone has purchased the BSR exhaust (or any other cat back system I don't know about) and if they are happy with it... since it is over $500, I was also wondering if anyone has just added an aftermarket muffler for sound improvement and the details/results with that... and finally you guys that have bought the dual tip system from Saab, how is the sound? Thanks for the help!

I haven't done anything yet, but mav238 has a magnaflow muffler and seems to be very happy with it (do a search). Again I think oslowley has the double-tip saab sports exhaust and has commented that it sounds better than the stock Vector/Aero oval exhaust. To my knowledge noone here has the BSR exhaust, though it would be interesting to hear from anyone who has.

Personally, I'm going to also go with a Magnaflow aftermarket stainless steal muffler in the next couple of weeks and will post some comments after I have it fitted.

Good luck!

WASAAB, where did you get the Apexi system? Is it online? Got any pictures of it on your car? Have you noticed any horsepower gains or improved throttle response?

I added a MAGNAFLOW high flow exhaust to my 9-3 about 8 months ago. Thus far, I am very happy with it, giving a very deep growl every time I rev the engine through the 1st 4 gears. Deceleration also sounded really cool, the rummMMM always brings attention. What I like about it is the non-ricey sound that some exhausts give, like those kids with the "DUNK" cylinder mufflers with the "6" round tips. I also went with a dual square 3" stainless steel tip. It gave a very European exhaust sound to it. Every heard an Aston martin drive by, sounds a little like that 8)

is it a full cat back exhaust system?

No, it's just the high flow muffler. The full exhaust system is a little too much for me.

cat, who needs that? would any sensors get tripped if there wasnt a cat? i think after i let everyone test out the mods and have some money to blow, im going to run a pipe and muffler, if that doesnt cause any problems with the computer.

Well I put my order in for a Magnaflow mirror finish high-flow muffler (also with the square tips like mavs). I will be getting it fitted on tuesday or wednesday. I have the valence cut-out already from the bodykit so hopefully my shop will do a neat job. Can't wait, I'll make a post with some thoughts and pictures next week.

Thanks to mav for the inspiration!, I tried a bunch of tips on for size and the square ones definately suit the car the best IMO.

Here's a picture of the tips from the magnaflow website, I'll post plenty of pics next week too when mine is done.

I considered getting dual 3" tips (round), however (thanks to Saba) I figured the valence cut (on the rear bumper skirt from the body kit) is around 9 inches so I wanted to be sure to give it enough room to breath so as it doesn't do any melting by having it move too much. Think this is the perfect size, after all I don't want to mess with the Saabish look too much :). I discussed tuning the sound a bit with my mechanic, we'll play around with it once it's installed - I'm looking into taking the resonator out or replacing it if need be.

These look great.
As for the BSR cat-back exhaust, i emailed them asking them if they had any dyno testing on their exhausts, and their reply was no, but the exhaust system will increase 3-5 horsepower on a standard engine. Doesnt seem a lot to me.

Yeah, it didn't seem worthwhile to me for the money. In addition to the increased airflow I believe the magnaflow units are much lighter than the OEM, I don't expect any performance increases but I have scheduled a dyno once my mods are done so it will be interesting to see.

What are you paying for the part and install (Magnaflow)??

moz
25th January 2004, 01:30 AM
The whole job is running me US $175 (part + installation). I did however get the muffler for a great price (think MSRP is $200+).

Anyone have any sudgestions on which system would be better, the Saab Sports Exhaust or the Magnaflow? Sound, size and weight, and hp gains? :-?

I'd also be curious about the effects on gas mileage. I have to believe that a more efficient air flow would result in better gas mileage.

This is hard to answer unless someone has tried both. I'll let the guys with the Saab exhuast post their thoughts but I did examine both options carefully. Firstly, Magnaflow has put a lot of workmanship and research into their products and it's generally accepted that their mufflers are of a very high standard compared to OEM ones. Also, as I understand the Saab Sports Exhaust is not stainless steel. I think the Magnaflow has a more aggressive sound, depending on how you tune it, but it's all a matter of preference.

I would imagine so, I'll post some thoughts next week.

Yes, theoretically, reduced backpressure does mean better exhausting of spent hot gases and making the engine more efficient. But this is only if you "tune" the exhaust from all the way where the exhaust manifold is located near the engine. By just putting in a high flow muffler, will not generate significant increases in engine performance. And this has to be coupled to tuning the intake and fitting a high performance ECU programming to make full use of the increased intake and exhaust.

I have not noticed any increase in fuel efficiency with the MAGNAFLOW, even with the ITG panel filter installed. But I am not sure whether my "apparent" feeling that the acceleration has benefited from these very minor modifications. I feel that the car does does much stronger now, again, maybe because I spent the extra buck on it. :cheesy:

The square tips installed on my MAGNAFLOW looks exactly like the one posted earlier. I thought about the single oval and dual circular tips, I think IMO, the dual sqaure tips give it the more European look (like the Remus mufflers).

Mav, does your exhaust ever scrape because it's hung under?

Mav,

Looks sharp! I noticed it extends below the valence without the decor kit. Have you had any clearance problems either from the bodywork or from the ground? How would you compare the sound to the oem part?

Wassab:
Just a question, what made you chose the Apexi over the more traditional oval muffler with dual circular/square tips or the single oval tip like in the vector?

I know it really ends up to, "to each his own", but I always find that mufflers like the Apexi, with tips as large as 4", fits more with cars like the honda's, Mazda's and Nissan's. In fact, that's where I find them installed mostly, never on European cars, or at least the near luxury cars like the Audi A4's, Volvo's, MB C-class, or even the bimmer 3-series. I certainly think the SAAB 9-3SS is at the near luxury car level. I don't doubt for a moment the sound and performance of the Apexi is at or above the MAGNAFLOW and the SAAB accessory exhaust. I just find that it doesn't quite belong to a car like the SAAB 9-3SS, making it look very ummm... ricey?? Again, JMHO and to each his own.

Yes, I chose Apexi N1, because I researched for the performance and found out that N1 Turbo Exhaust are the best for gaining HP/Torque..compare to any other exhausts..

I also knows that usually ricers got the N1s ..However, In Hawaii..It's got different taste..
Many BMW, MB, AUDI, VWs and VOLVO got Turbo N1s and N/A N1s..
Even, SUVs got N1 exhausts..
:lol:
I guess everyone got different tastes..
This time, I went for performance than the looks.. :P

Does anyone know of negative effects that a cat-back exhaust system can cause ?

mav238

Does anyone know of negative effects that a cat-back exhaust system can cause ?

I assume you mean one in which the factory cat is replaced as well with a high flowing one. In cases like this, there are no negative effects unless the new cat does not do it's job of maintaining the original emissions that the vehicle was tested at. It will not affect your engine ECU, ie. it will not trip your ECU to send an "check engine service" light, again, unless the cat you are replacing with is not the right one for the job. Most cat backs for japanese cars have been around for a long time, as is with VWs, and thus do not quite have the issue with emissions or tripping the ECU. But for cars like the SAAB, it will be better off getting one from a reputable manufacturer (e.g. Hirsch or Abbott or from SAAB if they offered one).

So would you say that the BSR cat-back exhaust system is reputable?

mav238

So would you say that the BSR cat-back exhaust system is reputable?

I believe BSR has been providing tuning options for SAABs for a long time, and thus should theoretically know what they are doing. There is a sensor in connection with the cat with which the ECU uses to monitor emissions and pop that "check engine" light whenever it detects something is not right. Most aftermarket cats are decent, but once you dabble into ones which are high-flowing, the designs become really complex and complex means issues can crop up if the manufacturer did not do it's design properly.

Basically, whenever you get into cat-back exhaust that also replaces the OEM cat, you must be prepared to put the factory one back on once the ECU is tripped. And if the dealer detects that the ECU was tripped because of emissions issue, and confirms that it was due to a tampering of the cat, the warranty may be voided. Just be careful, I guess.

A cat-back exhaust means the exhaust from the catalytic converter back to the muffler. Cat-back exhaust do not replace the catalytic converter. The cat on the 9-3 is connected to the turbo. You would have to buy a different downpipe to replace the cat.

joshd2012

There are some who offer cats that accept the probes. I imagine that there shouldn't be any problem switching to these high performance cats when they are sold by these reputable dealers.
