What is the sound difference between an o/r H and a Catted H?

 

A LOT!! From the factory we have a catted H. Put on an O/R H, and you will notice a big sound difference in both volume level and force.

 

Generally Hs sound good with a chambered muffler or straight through

Xs sound great with straight through, but not that good with chambered.

Cats play a BIG part in how the sound changes.
THe stock cats will not raise the tone of the FRPP X pipe with your mufflers. They smooth the flow.

IIRC the FRPP X direct replacement was most 5hp

 

Don't waste your money on a Catted H, because the factory is pretty darn effecient.

I had the o/r H and loved the sound but hated the smell. Then got a pretty good deal on the bassani x I have.

 

I should have been more specific. What I meant was, "What is the difference in sound between and o/r H and an H with high flow cats?" I know the stock H is very efficient but I want something a bit louder than the stock mid pipe.

What do you guys think would do well with MAGNAPAKS?

 

I think a catted prochamber would be awesome with the magnapack's, let me re-phrase, would be awesome with anything

 

How would you classify the prochamber: H-pipe / X-pipe / other? What kind of sound do you get with the prochamber?
