I recently purchased a '99 ML430 and am looking for a good exhaust shop to do some modifications. MB of Naperville would/could not do it and I'm reluctant to take it to a Merlin's. I'm wondering if anyone can share their experiences with me regarding mufffler upgrades or dual pipe modifications in Illinois. I live in Kane County but I'm willing to drive to anywhere but Chicago addresses. I see the posts about "body shops" around here but I want a true dedicated Mercedes person who is willing to know the factory mounts and do high quality work for a long-lasting result. I thank you in advance for responding in this thread. I'm new to your culture but not new to message/forum boards. I want to feel the love and not be subject to the typical newbie flames that I receive on other boards. I'm undergoing a significant mod project and have experience with other vehicles ('92 GMC Typhoon, '98 328i, '02 Xterra SE-SC). I'm obsessed with tinkering but exhaust work I cannot do.
