because he has a stock cb and h/c... if he had a good flowing cb that number would be drastically reduced... if he had a good flowing cb and no h/c it would have been <5rwhp

i have tsp rumbler, its basically straight 3" from y pipe back, if i threw a cutout on there id see 1-2rwhp at the most

I don't have a cutout yet...I was commenting on somebody elses results. I will let you know what a cutout does for me.

i ran 2 tenths quicker with my tsp rumbler catback .then with a cutout just after the cats on a stock exhaust. i thought it was weird, but thats what happened.

Friend of mine with Boltons TR Trak cam made 360rwhp through LT Headers ORY with Flowmaster catback after the Cutout it made 392rwhp.

nothing else changed not even the tune.

same thing kinda happened to a guy i know..he has a magnaflow cb with a cutout and on the dyno he lost power with the cutout open, also at the track his car was a little slower with it open

I gained exactly 11 RWHP and 6 RWTQ with my cutout open compared to running through my B&B catback on the TA. Cutout was under rear seat before the over the axle pipe.

Makes me want to run stock catback and cutout on my next DD again!

Camaro - heads and cam, hooker headers, mufflex y-pipe, cutout, and factory SS catback
cutout open netted 15 RWHP

I'm pretty sure we get good results from cutouts because our cam/heads etc.

I can understand possibly losing torque on the bottom of the curve w/ stock cam, cutout prob don't make much more power in the stock cam powerband

For the guys that run stock exhaust and have an electric cutout what size cutout did you use? The reason I ask is my car has the stock exhaust with a cutout on it. I bought it this way and now I am looking to get an electric plate for it and want to make sure I get the correct one. I can't go out and measure it being my car is still in storage. Would I need the 2.5"?

my cutout is right after the rear before the muffler i wanted it to seem almost like a cat back and it gives me alot less inside noise than the cars ive seen with the cutout before the rear. also gained like 1.5mph in the 1/4mile.

Maybe you missed this post

A catback and cutout will not be louder than just having a cutout.


Bingo.

Ive got longtubes and a a 3 inch y-pipe. I still have the stock muffler on my car and my cut-out is in the i-pipe. It's loud as hell in and outside the car when open but much more quiet that a car with a catback when closed. I can tell a difference in the tq down low when opened vs closed. It feels like the torque comes on sooner when it's closed as opposed to when open. It's an electric cut-out, by the way, for convenience sake.

thanks guys, i'm gonna keep my stock exhaust/cutout and get my buddy to weld up these vette tips for me until i get the money for headers/ypipe.

My cutout was gaining 10hp over my b&b tryflo catback on the dyno. Now with a 402ci I gain 22hp over the same catback when cutout is open.

when i was SI i gained 2mph with it open vs closed...

i accidently left it closed when i made a run I looked at the time slip like what the hell happened...lol
