prodrive, magnex, supersprint stainless, quiteSS.
Wich one is the more quite could it be possible to make some kind of ranking?

I have the same doubt, specially that I recently knew that a quiet SS existed.

prodrive is quieter than magnex but more restrictive.

not sure about the other two.

prodrive,ss quite then magnex

If you're just after quiet, also look at the Remus one. About as restrictive as the PPP one but quieter.
Don't know if you can get hold of one, though

 

I just fitted a scoobysport downpipe and quiet back box. The noise was quite loud to start with, but it dampened down after a day or too a little.

I run a Legacy Estate, similar arragement to a Impreza wagon, and found the noise from the boot floor to be the problem, a little boomy when tootling through my village, and flooring it at 70mph.

Today I fitted the spare wheel compartement out with dynamat (sounds deadening), and put 12mm foam sealing strip around where the lid fits over the spare wheel (lid was sitting on the wheel, otherwise, 5mm thick strip would be fine).

Now the sound in the car is just right, I can still hear the (nice) sound of the exhaust, but 70mph is perfectly civilised.

Quality and fit of both parts excellent, and remember shiny finishes doesn't neccesarily mean high quality.

This one is not on your list but it is the quietest out of all of them (Scorpion)

 

I have just fitted a back box to my WRX MY02.

After trying 2 that didn't fit properly from one supplier (not saying which one..) I then ordered from TSL-Motorsport. Paul assured me it would fit first time, not be too noisy-especially on the Motorway and not foul the body work...he was right on all of them. It's awesome. the noise is a low growl whilst off throttle but it sounds just excellent on full throttle!!

Oh, and it's also got a lifetime guarantee, even if you swap cars or sell your car on to someone else with it still fitted. full Gp N, gas flowed. My car is smoother with it fitted, and also seems to be doing better on MPG, which seems strange as I keep applying the louder pedal to keep my grin going..

WHICH EXHAUST WAS THIS?, AND HOW MUCH DID IT COST??

CARL..

 

Another vote for the TSL backbox. Got is fitted yesterday & has an excellent fit, finish & sound. Costs £305 fitted & well worth every penny. Speak to Paul on 0115 9377200.

 

I have a Magnex fitted to MY01 WRX ..

Defintely louder when originally fitted .. Now quieter or could it be I am getting used to it !!!

Is a Magnex really louder than a SS or TSL BB?

 

No idea if Magnex is louder, but I do know one thing....TSL have about 15 in stock, as of yesterday (Sat)..Magnex you will be looking at quite a wait for it to arrive in stock..

The TSL backbox is as loud as you would need it to be on full acceleration but nice and quiet when cruising on M'Way. What more could you want..oh decent service? Then TSL are the people..

 

Think I'll go with the TSL. From all the reviews it seems better quality than the SS and TSL customer service appears to be second to none. Thats good enough reasoning for me to buy.

 

I ordered a Magnex system (from the Cat back) 3 1/2 weeks ago, shouldn't be long now(?!?) Will review it for you soon...
