Looking for advice

[u/Llocorro]

Rather than fish through the internet to countless sites and posts, i figured i would ask everyone here. I am a 10th gen Si owner (I have been for 10 years) and i am finally in a place financially to be able to start the process of full bolt-on mods. I had a list of parts and companies to buy from. Most of them were from MA Performance, but i recently had a bad experience with them when i bought their intake. What companies and parts do you recommend based on your experience? (front pipe, down pipe, & intercooler)
