Catback and Headers

[Savage Messiah]

Don't get a direct fit convertor. Waste of money, get a high-flow universal. 3" cat to 3" catback, you may need to weld an extra couple inches of pipe... but ill post up pics of mine soon...

[KaotiKCamaro5]

my advice.. learn how to weld it yourself.. lol.. saved myself a chunk of cash that way..

So one for a LT1 will bolt up to my 305 directly, or will i have to do a little modification?

97CamaroRs, when you put your catback on did you notice any improvement?(i'm assuming you don't have headers yet) do you know what the average horsepower increses is there from just installing a catback with out headers?(5-10 im guessing)

To 97 again, i was just looking at how the magnaflow catback is setup and the pipe look almost identical to the way the pipes are ran on my 3rd gen, so i hope it is possible, cuz that magnaflow is beautiful.

Link85x, This is what you do...and you won't go wrong; either performance or sound-wise. For the cat, go with a Catco.
There are cheaper aftermarket cat's to go with, but Catco is proven
and it shouldn't cost you anymore than $150 installed.
Exhaust wise, you can never go wrong with a Flowmaster cat-back,
it's simply the best for the money. Last but not least, trash the idea
Edelbrock shorties. There garbage. There made out of cheap material
and the collector design doesn't make good top-end. I put them on my
'93 Z28 back in '99 and made 5.1 at the wheels. Go with SLP shorties,
nothing less!

Only 5.1 the wheels??? Whoa, thats bogus, you've got tobe kiddin, but i think those slps are actually cheaper or around the same price. I got the edelbrock catalog in the mail and it was selling those headers for around $650-$700, crazy!! I think slp's are around $400. Not bad. I was thinkin about gettin those 1st when i went there site, along with the slp cai.

Or trash the idea that you can never go wrong with Flowmaster. They are not made of stainless so they will rust through, their sound aint the best (even tho thats personal opinion), theyre not much cheaper than, say, Magnaflow (and I don't think Dynomax or Hooker is far behind there either), and the only thing that flows worse than flowmaster on our cars is the stock muffler.

Damn that sux, but i hope i can get that magnaflow catback, the picture i seen on performance peddler website was awesome, i want that catback.

GUT THE CATS! high flow cats are garbage

[Savage Messiah]

Yes, I noticed a littl eimprovement down low and a big diffeence up top, not gonna guess at #'s tho. Also increased my gas milage, IDK how much MPG but afterwards I've gotten around... 20-30 more miles to the tank.

Don't gut your cats, it's a dumb idea and you wont see much increase over high-flows. It is very loud and illegal (I will double check the fine but I believe tampering with cats [highflow you can get away with but gutting you cant] is around a 5 digit fine. Federal law.)

[KaotiKCamaro5]

eh.. i just cut mine off... screw it.. i hate cats anyways..

[Savage Messiah]

...
meow??

[Mr. Luos]

In my opinion......Flowmasters, or DroneMasters = Bad.

Magnaflow = Good

gezzus guys, my personal experience, i bought the IROC with stock exhaust manifolds, a welded in section of strait pipe where the cat should have been, and then it had a 3in "local shop special" exhaust system on it. now i dont konw about all of you, but i have emissions inspections and had to fix the exhaust system to make it pass spec. i installed edelbrock TES headers, may make changing plugs a bitch, but they sure as shit added power, i wish i had done a before and after dyno test to proove it, but i can assure you its a helluva lot more than 5hp in my car. Im running a catco direct fit converter (why in the hell would you make it harder on yourself fabricating all that shit when the prefit ones are direct bolt ins????) and i had to do a shitload of work to undo the damage done by the shoddy shadetree mechanic who did all this garbage to the car. then i had to torch off the fully welded exhaust system, and installed a 3in flowmaster STAINLESS STEEL american thunder system and tightened everything down. Ther performance was far better than strait pipes, it sure as shit sounded a helluva lot meaner, and the chrome tips look a helluva lot better. and ive not had a check engine light yet. only problem is again because the screwups who had her before me chopped her up with a custom job, i dont have the tranny mount for the exhaust system, so i need to get one to keep the exhaust from sagging in the middle. I am a firm supporter of running high flow cats instead of gutted ones, and seriously question anyone who claims to be able to feel the difference between the two.
