Cats... EAD performance has some metallic high flow cats at a good price. I plan to purchase these cats... im real excited about purchasing them cause from what i hear they barely cut down on sound at all. And they have a very high flow rate. Not sure exacty but its over 500 cfm per cat

ChocoTaco369

i believe the metallic core magnaflows flow at ~570cfm

dump the y and cat-back and go with duals.

which bulllet, and how much quieter is it going to make it...NO CATS

ChocoTaco369

a bullet is not going to work like cats. cats are your best answer. if you don't want to go cats, you will simply always have some rasp. your only option is to rip off the catback and run true duals. that's the ONLY way you'll ever get rid of the rasp without running cats other than running the super quiet SLP dual/dual catback. running a y-pipe, bitching about rasp, then not being willing to add cats simply doesn't work. putting a bullet in the I-pipe is like trying to put out a house fire with a squirt gun. there is simply no solution to your problem since you're not willing to comply to it. run metallic core magnaflow cats. you won't lose much horsepower at all, maybe 3-5 rwhp. big deal, you wouldn't even notice.

1) get some cats

2) buy an LT1

He said twice NO CATS, i beleive he doesnt want to run cats, ya think.

And I think the right bullet in the I-pipe will definitly help.

heres a topic that may help, theres more info out there, just search for it.

hey thanks man atleast someone can read on here, unless racer scott and chaco wana send me money to take my ORY off and put cats on which is gay with LT'S anyway it's not gona happen. Actually I'm gona keep an open cut out. Not worrying about bullet or anything. THANKS FOR THE HELP!

ChocoTaco369

really? because i addressed that statement, what, 3 or 4 times in my reply? there is NO REASON NOT TO run cats, other than a slight horsepower loss. that is literally the ONLY benefit of taking off cats, and in this case, we're talking a 3-5 rwhp loss. that is nothing. you lose 3-5 rwhp when the temperature rises 15 degrees outside. again, there is no reason not to run cats. i'd really like to hear his reasoning behind it, because it will be undoubtedly ridiculous.

a bullet in the I-pipe is like a band aid for a bullet wound. it'll help a little, but it'll still be there. ironically, he'll still lose a few horsepower due to the bullet if he goes this route. yes, the bullet is straight through, but it's a completely different medium and it slows the exhaust velocity down, resulting in a horsepower loss. so he's going to lose a few horsepower due to the bullet and STILL have rasp, so in reality, if he just would have went cats to begin with, we're talking a 1-2 horsepower loss

again, if you wanna run a y-pipe setup and are concerned about rasp, you have two options: switch to the SLP dual/dual or run cats. if you don't like these, go true duals. running a y-pipe setup on an aluminum block with a wacky firing order, being completely unwilling to run cats THEN bitching about rasp...well, you may as well shoot yourself in the foot while we're on the subject of pointless and bad things to do.

ChocoTaco369

you're gonna spend at least $50 for a bullet muffler, plus labor at the shop to weld in the bullet, resulting in a $100+ bill when all is said and done, and you're still going to have rasp. now, if you'd just spend $200 totaly, less than $100 more than you're already spending, you'd be virtually rasp free, lose barely any more horsepower and be legal while you're at it, plus you'll lose the exhaust fumes in standing traffic and a lot of highway drone. your logic is pointless. you're willing to spend over $100 for a solution that doesn't fully work, but you won't spend $200 on the real solution to your problems? makes no sense to me. really, it makes absolutely no sense!

i'll never understand it i'm trying to help you here. i'm giving you the real solution to your problem. if you get the bullet done, you'll still have rasp and be over $100 in the hole. for a little bit more, you'll have the real solution to your problems. i urge you to take my and others in this thread's advice and weld cats into your ORY. they're only $80/each for bullet cats that will fit nearly anywhere and won't hurt ground clearance, tone or horsepower much at all, but will help cure your rasp problem. take the advice, do the smart thing. if not, again, you're patching a bullet wound with a band aid. best of luck to you.

and haha for the 4th time this post NO CATS

ChocoTaco369

then for the 4th time in this post, no solution to your problem. you will always have rasp forever.

1.) add cats
2.) get an SLP dual/dual catback
3.) go true duals

those are your three options to remove rasp. if you're not willing to do them, don't complain about the rasp. i tried.
