84 K25 Exhaust Opinion

[rambo84k2500]

I want to hear some opinions. Curious what ya'll think.

I currently have a 1969 327 small block in my 84 k25 high sierra.

Decided to put on ram horn style exhaust manifolds cause I needed something worthwhile that would fit my 4x4 chassis with mechanical clutch linkage, so I decided to keep it simple with new ram horns.

New ram horn had 2.5 collectors, so I had the exhaust shop put on dual exhaust.

Here's the opinions!

I wanted my truck quiet so I saw that squarebody trucks with the 454 came with quiet-flow 2.5 inlet/2 outlet mufflers. If that muffler is okay for a 454 should be okay for my 327. Now I have ram horns with 2.5 dual exhaust with 454 mufflers.

Well my local exhaust gave me some s*** for putting on those mufflers. Said it was to restrictive. My truck runs great and is quiet now. What you think. Curious. Are those mufflers to restrictive???
Down the road I'll put in a fresh 350, but even a stock 350 my exhaust should be fine, I think. I can always change to performance mufflers down the road.
