dont waste you money on an underdrive pulley. I have one on my car and I saw 0 improvement in 1/4 mile. what other mods do you have on your car?? If you have full exhaust the cutouts not really going to give you much improvement but it will ain you more then the underdrive pulley

almost full bolt ons minus pulley cutouts dr's. I have the kooks lt's to the slp lm exhaust with stock cats.

get some dr's first. you will see much better gains with them. You might get a tenth from the cutout if your lucky. Good luck with your car man and glad to see a new member

Yea with that LM I don't think you will gain much HP. You could always take off the I-pipe and run it like that to see.

My car gained 10 rwhp on the dyno with the cut-out open vs. through the cat back. I have the graphs to show it. LT's, ORY, 3.5" Cutout, flowmaster muffler. LM will flow better than the quiet flowmaster though.

Yeah thats what I was thinking bout 10whp..I'm running stock cats so I was hoping thats where the extra power would come from bypassing them??

Id spend the money on some high flow cats if you really need them or an off road ypipe would be an even better choice. That with a resonator in the Ipipe would help with rasp and net you the best gain for the money. You have great headers and a very free flowing catback but those stock cats are holding all that potential back. ORY would help tremendously. Cutouts arent needed unless you are running full exhaust with a crap load of power or stock exhaust and want a cheap route to get the exhaust gases out quickly. Its silly when you already have long tubes and a great catback. Cutout is more for sound at stockish power level IMO.
Plus you would need two cutouts to put in front of the cats to work properly. For two electric cutouts, thats $400. Spend half that on an off road ypipe with a resonator and have all that power all the time and a great sound 24/7. Then you still have $200 to spend on something else for the car like a rear set of DR's or suspension parts (panhard rod and rear control arms, etc). This is the route I would take.

i picked up .15 sec and 1.5 mph with the underdrive pulley for 210$ and an hour install it's worth it. i used a kit from scoggin dickey, pulley, belts, and arp resueable bolt. it was either the slp or the powerbond, and yes it was the only change. don't know about goats but i took an easy 100lbs off my 01 camaro.

The asp pulley is smaller and lighter and will make your car's rpm's spin up faster. It also is less weight that your motor has to turn. Get the pulley then a cutout later. I feel the ASP pulley is the one to use and when i weight it next to the slp and the factory it was the lightest.

there ya go if the asp is noticably lighter it could be a full .2. definately worth it. i would get worried about the dampening effect if it was to light though, but should be good for a stock bottom end car. by the 60ft tires would be the biggest help but thats more $ then both these options together.

Just mentioning, it's best to do a U/D pulley when doing a cam and if thats not what your planning to do now, a Cutout would be a better alternative either way.
