Side Pipe SPL

[Machiavelli]

Welp, I heard 'em - who can recommend a good ear plug? Not obtrusive at idle, but let's face it - the neighbors WILL here me leave at 6am (unless they're blessed with a wife that snores like mine). But as with any fact finding mission I undertake, there is always a new question that arises. Ceramic coated aluminum vs.stainless steel? Big dollar difference there, but if stainless with internal baffling is a "good for a lifetime" proposition (like ERA thinks), then it becomes a trade study of cost & time to repack and/or replace vs. install and forget (except for the occasional polishing to remove yellowing or bluing). I did mention this to Larry some time ago, if I recall the conversation - there were other issues with stainless steel that didn't make spending the extra $$ a worth while consideration. I can go either way, but for the extra money stainless steel does need to last a real long time.

Told you so..............

Stainless is a waste of time and money for the application. Aluminum cannot be used due to temperature.

Mild steel is the choice.

Ceramic coating lasts a very long time and is maintenance free in my experience with it.

The thing to pay attention to is the length of the actual muffler section. The longer you can make it the quieter it will be. (Relatively speaking of course.)

The cost of the sidepipes is actually quite low and I recommend one for road use and another for track use.

But per your post about Laguna you may wish to just have the street pipes as Laguna has a pretty low DB limit and race pipes might not make it past the noise cops.

Thanks Richard, that's probably what Larry told me but I couldn't remember. Didn't know Laguna was touchy on noise, but makes sense, the race track is in a canyon so mountain echo must be a real problem. I'll ask Larry to go with the longer muffler if there is one.

Check with Eric at Classic Chambered mufflers. He has a variety of options on length and inside diameter....so you can decide the best mix of sound vs. power

jdean,
Just went to their website and checked them out, sounds like a real good solution. The performance gains they have posted do seem high to me. Are you running these pipes, and if so what's your opinion of them? No mention of ceramic coating on their website, but I imagine a recommended last step. I'll give Eric a call and get some more info, thanks for the tip.
