Their continued development of the B8 platform is not limited to FMIC kits or Turbo kits, their all new catback exhaust system is evidence of that. The CTS Turbo B8 S4 catback exhaust system is hand tig welded using the finest T304 stainless steel.
Each CTS B8 S4 catback is 100% tig welded, constructed using T304 Seamless Stainless Steel, and includes installation hardware and stainless steel clamps. Lesser products can be had without stainless steel construction, or with seamed stainless steel, which can crack and decay over time. The CTS Turbo B8 S4 catback increases turbo spool up, and peak power.
