W203/CL203 Aftermarket Exhaust Thread - All you want to know
I believe it has to do with a very fast and short exhaust stroke of the Nissan powerplant coupled with the whole exhaust system being tuned to a higher pitch. Someone please correct me if I am off base here. I just remember either reading or hearing something about why those cars sound the way they do.
Also, did y-pipe the piping from your secondary cat? Looks like he put on two mufflers, so that it wouldn't be obnoxiously loud, thing is for a force induced car, that length of dual piping may not be "ideal" for airflow.
I can see why it cost as much as it did though, based on how they did the piping.

wait so do you think there will be a lot of back pressure in the future?
yeah its pretty loud the way it is already...similar to roland's, but noticeably louder than his.
I also measured the pipin on my coupe which is 2 1/8 all the way except for the inch before and after the cat & resonator which is 2 1/4
thanks

Kidding..I used to think that way and when I had my old Magnaflow muffler,the car sounded alot louder, but didn't feel faster and still had the lag LOL
surprised you didn't just go for the Weltmeister at $990 from performance products.how does it sound? I'm sure drex mentioned it before. running two muffler's gonna kill your exhaust flow.
it sounds very deep and throaty...rumbly...then at WOT its gets loud and deep...you could still hear the supercharger doin its thing, but yeah overall its loud and deep.
in terms of flow, im hoping when the exhaust really breaks in, i wont experience any backpressure, which drex says wont happen...only time can tell though...

I think we been through this. Please post the Magnaflow model number so people can check the spec. and don't get stuck with something that won't pass smog. Now if they plan to use it in a racing application, of course it won't matter (but they wouldn't need it at all if it was for racing), or even possibly in other states.
I'd love to see you sell this, just don't want to see a member buy it, pay 100 bucks to get it welded in and then fail smog since the primary reason they'd be buying it is to replace a faulty one thats failing smog.
