Loudmouth 1 Resonator Is the loudmouth 1 resonator just a pice of straight pipe?
I am thinking it would be cheaper to run a straight pipe instead of dropping $50 plus on a pice of pipe. Haha. Would there be any noticeable sound difference?
Thanks guys.

Thanks mesterious.
Im sure the sound difference would be minumal. Loudmouth 2 looks similar to a dynomax bullet. I think I will just use pipe for right now. Haha.

i did just that back when i had my trans am. straight pipe dumped before the axle (with headers) sounded good but with a dynomax bullet it sounded KILLER!!!!!!!! 50 bux? you can find some bullets for 35 to 40 bux. its worth it, like mesterious said, it will sound different.

Here is letter SLP includes with every Loudmouth Catback System.
Dear SLP Enthusiast,
The SLP Loud Mouth (PN 31044/31044A) DOES include a muffler. While it does not “look”
like the traditional muffler, it is indeed a muffler by definition.
The muffler (aka resonator - actually a misnomer or ill-understood word) was designed by
SLP to smooth the exhaust gas pulsations by methods of wave rarefaction to make them as
inaudible / quiet as possible. This is a type of reflection muffler; Most people are much more
familiar with more common 'absorption type mufflers', which typically include internal
perforations, sections, and/or absorption insulation.
More simply put, a muffler exists and was designed with intent to reduce exhaust noise.
The Specialty Equipment Manufacturers Association (SEMA – www.sema.org) has staff
dedicated to representing the aftermarket industry in regulation/legislation pertaining to
aftermarket parts. SEMA is an excellent source for further information and/or news and
updates regarding the latest laws governing aftermarket parts.
The SLP Loud Mouth exhaust system is 50 state, emissions legal. It will
not adversely effect emissions. Every local jurisdiction creates and enforces
their own laws regarding ‘noise’. Local jurisdictions have the ability to write
more detailed and stringent laws regarding noise - but commonly do not
outlaw 'replacement exhaust systems'; Unless they have their own specific
design criteria for a 'muffler', which specifically excludes reflection type
mufflers, the Loud Mouth would typically be acceptable. Only actual
laboratory decibel measurements are a fair measurement of a muffler’s
effectiveness to quiet exhaust and should be required and completed to
judge an exhaust system. Most jurisdictions do not have the ability to
measure noise levels accurately. The testing is very subjective if not
properly and accurately completed.
Due to the nearly infinite number of local jurisdictions, ‘related noise
regulations/laws’, and their high frequency of change, SLP does not
participate and/or represent customers, companies, shops, technicians, or
sellers in any litigation, traffic or legal matter regarding or related to the
legality of an SLP exhaust system and disclaims any responsibility. It is
solely the responsibility of the customer to investigate and verify whether or
not SLP products are legal for use. SLP recommends checking local
legislature for specific laws regarding the legality of aftermarket exhaust systems.
Both Loudmouth systems include a muffler, not a straight pipe, that is designed to reduce exhaust noises, which is the opposite of a straight pipe.
Therefore, neither of SLP's Loudmouth Systems are the same as a straight pipe.
