i know alot of the truck guys are running cutouts. did anyone get before and after 1/4 times?

also...explain your motor and mods, and if the times were in comparison from stock vs. cutout or aftermarket vs. cutout. if aftermarket, what setup?

just tryin to feel this out

 

i installed a single manual 3" cutout about 1 foot from the stock Y joint. i picked up 2 tenths vs running through my flowmaster. tune, pulley, cai, plugs, wires, efans, cam, gears, street tires. on the same day i tested it open and closed. every time i opened it i would be 2 tenths quicker in the quarter than with it closed. granted, i have a flowmaster so i am sure people with magnaflow or other high flow muff won't see that gain. but for 30 bucks, and 20 to have it welded on, i was happy. plus it sounds better.

 

Yeah, there has been a lot of questions regarding this. I think, and this is just my personal opinion and from what I have seen from others, that you would see a gain from cutouts over stock exhaust or even maybe flowmasters or other similar exhausts. Magnaflow, dynomax or other straight thru design exhausts may yield a gain from cutouts, but it will not be near as much say over a stock system. I have seen many use cutouts over there aftermarket exhausts lose a little even. So its just kind of a crap shoot. But the price for cutouts is minimal unless you decide to go electric, so you might want to try it just to see.

 

i already have a manual 3" cutout on my stock pipe and muffler. i never took it to the track on the factory exhaust though. i planned on taking it on and off last time i was at the track but left my wingnuts at home . i feel like it gained, but my SOTP meter has been known to be thrown off due to sound.

 

TXsilverado, how far away from the muffler did you install your cutout? I was looking at my truck and there is a nice straight length of pipe just behind the Y-pipe flange. Just wondering where you guys have them.

 

im in an extended cab. theres a bar that crosses between the frame rails that it sits right above. the dump comes pretty close to next to the muffler.

 

who sales 3" cutouts???

 

Texas Speed and Performance has them>>>>>>>>>>>>>>>>>>>
There may be others as well.

 

i think mine is qtp (www.quicktimeperformance.com). they're a sponsorer.

 

o3gmc lost time with his cutout, im sure he'll give the details when he sees this.
