From someone that is desiring to build a Dinan ZHP, I love their products. Honestly, you can get much better bang for your buck with other manufacturers. But, Dinan products are phenomenal quality and I've been super impressed with the intake and exhaust (the ones I've put on my car). Dinan is perhaps considered more 'old school' but their mods are very understated and classy I think. If you like the mods, awesome, keep them and enjoy them.
Speaking of, do you know exactly what mods you have? I see intake, exhaust, and strut bar. What others??
