Thinking of re installing stock WS6 catback, bad idea ??
Hey ,
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 actually really love the sound but I cant floor it in town anymore without getting ALOT of attention. I have cats so the sound is quite a bit more refined than with ORY. With the windows up it doesnt drone , sounds quiet . .. but outside its like I opened up the gates of hell at 6500 rpm
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....

SS catback is not the same as WS6, my friends SS catback was 2 1/2" whereas a WS6 catback is 3", conversion was done by two completely different companys. (SLP & ASC)

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

I stand corrected, I have just read alot of posts saying the WS6 catback flows very well??
But that's why I'm here, to learn
i have a 01 ws.6. when i added the b&b try flo catback i only gained 3rwhp(thats right 3 hp was all).if you buy a catback keep the stock one in good shape,you may need it again. goodluck to ya.
The WS6 exhaust flows very well. It just wasn't loud enough for most. GMHTP did a comparison with a few aftermarket kits and found none of them did better than 5rwhp over the WS6 stock system. So sell it.
Popular Hot Rodding or GMHTP did a B&B TriFlow install on a WS6 & got 1hp.

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

The reason they only got 5 HP out of a B&B TriFlow is because the TriFlow sucks donkey ***** and barely flows better than stock
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 can't argue the merits of stock WS6 exhaust versus aftermarket power losses/gains but I can say that with my cutout open I only pick up 7 rwhp and 6 ftlbs.
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.
