If JIC were to ask me what one thing I would change about the exhaust if I could, my answer would be the restriction at the mid-pipe.  The pipe choked down to 2.5 inches where it met the downpipe.  I was unaware of this restriction when I purchased the exhaust system.  While this allows the catback portion of the exhaust to bolt up to the factory downpipe, it would be a significant restriction when upgrading my downpipe or adding performance modifications in the future.  This drawback required a call to JIC.  When speaking to their technicians about it, they suggested that I could take some 3" inch Titanium piping and add a 3 inch flange in place of the 2.5 inch section of the exhaust.  While this is less than ideal, I know a competent fabricator can modify my mid-pipe to mate the exhaust to a 3 inch downpipe without any restriction.

In sum, JIC's customer service is outstanding and the product was of exceptional quality, which is why I am completely satisfied with this JIC product.  I feel confident in recommending this exhaust to other STI enthusiasts at www.iwsti.com, and I feel it is worth the extra money for the titanium material, quality, weight savings, no-hassle installation, and sound unless you want a 3 inch titanium catback exhaust that needs no additional modification to work effectively with a 3 inch downpipe and flow the most exhaust.

The last thing I would like to add is that every enthusiast has different needs and wants, and as a result they will rank criteria differently.  In fact, a number of other factors that we did not go into in this article could be used.  I hope you can use this article to ask the right questions so you can make an informed decision about which exhaust is right for you.  Feel free to drop me an email if you have any questions.
