Thinking of re installing stock WS6 catback, bad idea ??
I have kooks headers, kooks catted Y pipe and slp loudmouth catback. How much power would this kill to put the stock WS6 catback back in there ?? I heard it actually flows quite well is this true ? Has anybody done this ?
My car dynoed 390 rwhp with the current exhaust . . .. would it be more than 5rwhp loss ??

Bro, hopefully you know better than that. Expect to lose 15-20 through a stock catback with your mods. (BTW, the WS6 catback doesn't flow any better than the T/A catback).
The Loudmouth catback SUCKS after getting headers. I'm assuming you want something quiet? If so there is a lot more options out there to quiet the car down and not lose power. Putting a stock catback on would be the worst of those ideas...
I like the idea of a stock exhaust behind a stout set up but ONLY with a cut out for when all the power is needed.
I miss being able to mash the gas everywhere . . . .all the time

But IMO it sounds like 25 Ducks getting poked up the *** around 2500 rpms without cats....

I was given a WS6 cat back for free and will probably mount it to my 395. The $200~$500 I was going to use for an after market cat back can be applied else where for now.

15-20? More like 5-10
The catback flows much better than the stock TA piece, not sure where you got that idea.

The WS6 catback with a cutout would work, but expect to lose a minimum of 10-12 rwhp over what you've got now through the muffler....
No, I am not saying a catback will give you 15-20 HP. I am saying with a internally modded engine, a stock muffler will rob 15-20 HP through full exhaust, as to where a "better" muffler would only rob 6-10 (FWIW, my Hooker exhaust only pulled 4 HP out of my 476 rwhp setup vs. the cutout).
I've been there and done it, like 4 yrs ago....I feel like a newb arguing about a stock muffler

omg that description rocks
now back to the subject yes you will lose power
10-20 is norm for stock cat backs, if you need quiet get a dual dual very quite even w/o cats and wont lose as much

If you want a good comparison, I gained 15 rwhp over my SS muffler going to a Hooker catback system on a stock internal motor.
TriFlow is a HORRIBLE flowing system..
I'm running a H/C,LT, bolt-on, M6 car making 402 rwhp through the WS6 exhaust and 409rwhp with the cutout open. The beauty of this setup is that my car is not that much louder than stock(which I think is pretty healthy sounding) and I picked up two spare complete WS6 exhausts for free off guys replacing them.
