I am going to get the Dinan S1 package on my 06 4.8is. The only draw back is that I LOVE the oval pipe look and don't want to elliminate it with the dual-tip product that Dinan offers. Does anyone have experience w/ how the Dinan intake, throttle body, and other components would work w/ another aftermarket product such as the Eisenmann oval tipped exhaust? Any other pipes I should look into out there?

Thank you much X5world!
