Cool. If you havent scraped the stock exhaust, i think you should be fine. Tony will probably let you know before you leave the shop if he expects it to scrape. Good luck
I love how it looks. The back could be lowered a tiny bit more though. I too wish i went with coilovers. Unfortunately, Im number #621 and dont get it until the end of November. After i get my exhaust though, ill be switching over to coilovers and selling my H&R's. The springs could be a little more stiff, imo. Id be happy to let you know how the exhaust is after i get it. From what Tony has said before, the FI TDX sits a tad higher than stock.
How do you like your springs? I have the same set up and love how it looks. The stance looks great.....but there are times when I wish I had coil overs. I'm goin to have mine checked out because I files like it rubs too much because it is so damn low.
