Help me make a ss exhaust decision

[genphreak]

Bo--my current muffler and resonator are rusty and flaking from their former life on the east coast even though she was a garage princess. The rest of the underneath is really good. I want stainless for the sound. It is all about the sound. In CA, what I put on should last an eternity since it never snows in San Diego.

Vinny--The indys who will be installing it made the point that not all stainless is the same. What do those numbers mean? Which are good?

Nick--I am probably going with the stock resonator after what I have learned in this thread. I appreciate the reinforcement that a 535 can't go without a resonator. I also appreciate the info about the 2" and 1.5" or 1.75". I figure you can never have too much information to make sure something stupid doesn't happen. The indy was in favor of supersprint and I am probably going with the eisenmann so I need to watch my own back. Thanks for the help.

SOunds like a good course of action but I love the wastegate idea- I think it helps with low-end torque too. It is standard on that stock non-turbo Nissan so it can't be a bad idea. However I can't help thinking I saw a full banana-bent (OE style) full SS resonator somewhere recently... the SuperSprint is just like the generic unit my Indy stupidly put on my car which is the only reason I don't like it. If you do go this way, call SuperSprint directly to be sure they don't have a new design or a version with SS case (I am sure they can make it). The banana type one I saw was awesome... just can't think where it was...
Sorry!

Here is the supersprint resonator and muffler. Is this what you were talking about? The reason I am leaning toward the eisenmann is the supersprint is only slightly louder than stock and I am after the sound.

And here is the eisenmann in case you want to see.

Yes those are the ones I know. The Supersprint one is the one I suspect might be available with the more exotic resonator. The resonator Eisenmann have looks basic like the Supersprint but is probably full Stainless. The Supersprint only states it's has a Stainless interior... Then again, this special one I've seen might not be supersprint or eisenmann, perhaps its eberspacher or something.... sorry I can't be of more use.

BTW- To anyone that's interested- I spoke ot my friend with the Skyline and it's wastegate is mounted inside the factory Stainless muffler. It works on engine speed, only opening the second tailpipe when flowrate requires it. I'm going to see if this can be incorporated on the E34 somehow, for 3reasons:

1) I suspect the E34 requires some back pressure to maximise scavenging efficiency of the stock manifold
2) Cos it's a pretty sweet way to avoid the cops harraunging you at the lights
3) The car roars at WOT and is streetable at other times. My preference- but perhaps not Gayle's!

Hey Gayle, perhaps you should go see the peeps at SuperSPrint or Eisenhaus and let us know what they say? Nick

i vote big old loud B&B triflo. no isseus with build quality - top notch. sure to wake your neighbors up.

I installed a SuperSprint on the M5 this summer. It is quite a bit louder than stock, especially at idle. High RPM yields one hell of a shriek. All in all, very pleased with the results.

Make sure you keep a resonator in there. In this case, the resonator is straight through, just like the rear muffler.
