Again, I can't say enough about how awesome everyone is at TSP. Corey Poole has been a tremendous help providing guidance on building my 23 Civic Si. I can't reccomend this group enough. I have purchased the following items from TSP and have zero buyers remorse 1. Spoon N1 exhaust 2. TSP turbo down pipe 3. Titanium turbo inlet pipe 4. K-TUNER with tune and case 5. Titanium studs for multiple locations I have also purchased a number of components from PRL, but this was before I found TSP. There is nothing wrong with PRL, I just like dealing with Corey. I trust his knowledge and he's very personable and professional. Generally a cool guy that I look forward to dealing with as this build progresses.
