Hi currently have a stage 3 in for custom mapping & was told the rear Miltek Catback (Resonated) was restrictive. Advised to replace for BCS full system.
Popular opinion is that BCS systems are the best performance-wise followed by the Milltek etc, which I agree however did not see the need for a new BCS system assuming my 3" DP decat joined to a 2.75" miltek cat-back is sufficient for up to 450bhp based on the fact that there's a TTE420 thread with over 30 stage 3+ cars with briefly listed mods for each car, almost half of the cars have Milltek exhausts in the list (assuming only cat-backs) and achieved 400-450 bhp.
Just wanted to see some opinions/experiences to why people think these are restrictive & if so what Miltek systems do these TTE420 cars have? last I knew for the 8P S3, MK6 R & GTI. Miltek only offer two variant (Resonated vs Non-Resonated) systems that all share the exact same rear box MSAU346 which is claimed to be restrictive performance-wise?
Please keep the discussion based on the performance aspect of the exhausts & not the sound.
