Guys, i have been in contact with Grizz and i am willing to buy some stuf from him. So i am looking around the internet to see what can i buy to make better my RS. So i have some things i would like to order but have no idea if they are really good. So if you can write some information about the following to make my choice to buy or not to buy. Thanks a lot for any help
1.- Sport cats 100 cell (wanna improve the sound--if i put it what will improve?)
2.- Silicon Kit for Turbos( they wrote me that they are better for turbos--not really sure why)
3.- Wagner intercooler (what will change when i replace the OEM with these ones)
4.- ITG filters (what will improve?..i have the KN on and really NOT happy)
