I'm in the market for a GESI/Euro 6/HJS downpipe that is also low on the noise.
I know that cast dps are quiet due to the heft of the connection to the turbo, but unfortunately it appears that no one makes a cast downpipe that also has a resonator and a high end cat on it. I know APR did this, but it's now discontinued and I'm also not a big fan of their o2 sensor location and requiring a tune to wipe CEL errors.
Alternatively, I'm seeing normal non-cast mandrel bent DPs feature both high quality cats and resonators (e.g. MAP performance). Does anyone know if I can expect the same amount of noise from a cast DP vs a non-cast DP+ resonator?
I'm just trying to decide between MAP performance (non-cast+resonator) vs say Miltek/Cobb (Cast but no resonator). Any insights or opinions would be appreciated. Thanks!
