Hi,

I just got 3" catless primary downpipes installed w/stage 2 BM3 (skipped the downpipes, didn't want the smell).

After installed I can now hear a definite whistle sound which wasn't there before. I assume it's the turbo spooling. I initially was planning eventually adding the Eventuri intakes, but questioning if it's even necessary now? Will the sound stay the same ? Any one else have catless primary downpipes w/ eventuri intakes?

Thanks!

Eventuri definitely makes the turbo sound more pronounced. I had the intakes before the DP and it did get a little louder when the exhaust valves are open but definitely didnt add as much as the intakes.
