  1. Installed a 3" cat-back rarely seen here... Pics and video. Thermal R&D

    Quite a bit louder than stock, and a much deeper tone at idle, but cruising there's almost no sound inside the car. It's perfect.
  2. 20% OFF Thermal R&D here at Lethal Performance!!

    Yeah the Borla Type S was insanely loud. Could not even have a conversation while driving. Hehe.
  3. 20% OFF Thermal R&D here at Lethal Performance!!

    It's awesome in every way. Best hidden gem on the market. Enjoy!
  4. How do I quiet down cold starts without a tune?

    Coyote definitely has a "bark" that no version of the 4.6L or 5.0L ever had. I think that's largely the 12:1 compression ratio. Remember we were at 9:1 and earlier smog-era were even lower. Direct injection is what allows the insanely high compression ratio, which is also a big reason for the...
  5. Air Lift 3P Questions

    Oh I also have the factory spare tire/jack kit and am not interested nor willing to take that out.
  6. Air Lift 3P Questions

    Any recommendation for an expert installer at your caliber in the Houston, Texas area or maybe San Antonio or Austin? Just not interested in letting someone do it who hasn't done it on at least 10 or more S550's. Not someone's beta tester :P I figure you might know people in the business. I...
  7. Best Tire Brand and Size for Staggered Setup

    I'm enjoying my Firestone Firehawk Indy 500's so far, but they are a summer tire and I don't really drive much in the rain.... they seem to grip great on hot dry pavement and look amazing. 325/30-19 rear (on 19x11 SVE wheels) 285/35-19 front (on 19x10 SVE wheels) Fit perfect.
  8. Steeda Dual Rate springs review

    Air bags then?
  9. Catless exhaust setup solutions?

    For a full stainless 3" mandrel-bent beautiful exhaust, it is THE best option for non-active cars. No idea how they're doing it and making money and/or Borla/Corsa are r@ping owners for their exhausts, which cost exactly the same to build.
  10. Catless exhaust setup solutions?

    Basically if you want a compliant exhaust, rule out EVERYTHING that Corsa makes and only consider from Borla the Touring version. Everything else with headers in front of it is going to make your ears bleed. The Thermal R&D is on the milder end of that scale, but only would recommend if your...
  11. Steeda Dual Rate springs review

    Can someone specifically explain or provide a link on what "clocked correctly" means? Considering between the minimum drop springs (Steeda) vs. maybe an air ride kit (on the extreme other end). Do NOT want a slammed car and do NOT want a car that rides worse than stock. At all. Not even a...
  12. Catless exhaust setup solutions?

    Just called them, it is an American company out of California and real people answer the phone. I think the guy spoke to was named victor, it's not like one of those weird conglomerates or international companies, it's literally a California company just called them.
  13. Thermal R&D exhaust

    Hey, yes I got it installed. Unfortunately I wouldn't be able to give you a comparison with headers, because I still have stock manifolds and cats. I have heard that this system is the ideal one to have if you want headers and don't want to make your ears bleed. Thus far I absolutely love this...
  14. The OEM+ Daily Driver in Orange Fury

    Absolutely the best non-active 3" catback you can buy, and 1/2 the price of Borla.
  15. Another Gen 3 Coyote Knocking?

    What do you do just unplug it?
  16. Which exhaust would you pick and why?

    I did say that, the car has been put away in the ugly weather, though. Forthcoming!
  17. Which exhaust would you pick and why?

    The quality on the Thermal is unbeatable in this price range for a full 3" Cat-Back!!! Just do it.
