encourage you to read our catalog and the info on this site
thoroughly. We have made every attempt to provide as much information
as possible to help you make an educated decision about your purchase.
We do not know every exception about every vehicle, but we do try to
communicate known exceptions wherever possible. As we put the various
System Kits together, we anticipate the most common situations, which
normally will cover over 95% of the installations. There will always
be exceptions, which you may have to deal with during installation. IF
you can put some "before-hand" thought into your purchase, then the
possibility of being caught "off guard" during installation is greatly
Our Qualified Guarantee is that our
systems will fit as long as there are no complications with header
alignment or other aftermarket devices.
We cannot guarantee fit if your headers are angled differently,
shorter or closer together than the typical header, although we have
made several items which can help you adapt, if necessary, with your
installation in difficult situations. Different wheelbases also create
the potential problem of coming up short with the headpipe length on
dual systems. Although this happens rarely on most vehicles, we have
available, extension kits and longer Headpipes (HL Series) that can be
purchased with the system or later at time of installation.
IF our system does not fit OR you
feel you won't be satisfied, then we'll refund your money -- no
questions asked. Just return any new or unused part within 90 days of
the shipping date and we'll refund the purchase price. (Shipping
charges are not refundable). We cannot accept return on custom-ordered
or special-ordered parts.
Fitting Problems: If you have a
problem with fit, we ask that you call our Tech Line for assistance.
We should be able to help you figure out what to do. It is very rare
that any of the pipes will be bent incorrectly. We have learned from
experience that it is a waste of our time and yours to JUST SEND
another pipe. You usually always will still be faced with the same
problem. If you want us to check the pipe, we will. Just return it
(properly insured) and we'll check it out. If it is indeed incorrect,
we will promptly ship a correct one and reimburse you for your
shipping expense. If the pipe is correct, we will ship it back or give
you the option of a refund (your choice).
C A U T I O N
Before cutting any pipes,
MAKE SURE everything is going to fit and if not, decide what is
necessary for them to fit. Remember, we do guarantee fit, but that
guarantee is made assuming certain things about your headers and
vehicle. Anything out of the ordinary, will naturally cause problems
for installation. That is why we always allow for returns without
restocking fees if you think the system will not fit as you would
like. Along with this guarantee, we expect that you will return them
uncut and undamaged.
Rarely will there be a pipe bent
incorrectly. We have been selling these systems for many years now and
they have been fitting the stated applications, so we know the design
is a proven one. Usually, if there is a problem with installation, it
will be because one or both headers are not pointing straight back (in
other words, they may be pointing inward, outward, downward or upward
OR they may be pointing straight back okay, BUT just be too high to
easily hook up any exhaust system). Now we know this isn't your fault,
but it isn't ours either. BUT, we can help in these situations,
because we have developed some alternate products which can often
help. If we can't help and/or you just plain don't want to worry with
making any adaptations, then you can return all or just part of the
system for a refund. We don't expect you to keep what won't work or
what you just don't want.
Sometimes, tailpipe installation can
be complicated somewhat because of installation problems from the
mufflers forward. As you are trying to correct any problem up front,
always keep in mind tailpipe positioning, because they will be
Of course, you can always return the
system or any part of it -- no questions asked. We just expect that
you will return it in the condition you received it -- unused and not
cut or damaged! That is why we CAUTION you to check out your situation
FIRST, BEFORE cutting. However, if you have a problem and the above
info does not help, we encourage you to please call and we'll do what
we can to help. We may be able to offer some possible solutions.
If for any reason, you want us to
check any particular pipe for correctness, we'll be glad to. If is
indeed incorrect, we will send a correct one to you at our expense and
even pay for your shipping it to us?
Please keep in mind that the bigger
the pipe, the harder it becomes to adapt -- bigger pipe and less room.
As always, we appreciate your purchasing our product and always like
to hear from -- even if you don't have a complaint.
