Whipple owners... Hi flow or race pipe? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Hey just a quick question to the whipple owners, what do you run hi flow cats or a straight thru race pipe? Also what's your power level and mods? Thanks

We suggest running catalysts on all supercharged vehicles, up to a certain power level, especially with the twin screw/roots style for the added back pressure. Max effort cars may end up blowing out the catalysts when making big big power.

We typically run LT headers and supplied cats

Pretty much the opposite of what others are saying. Ask all the guys who melted their cats and blew up their engines...

I justed gutted mine, don't want to take the chance.

HumanWiki · 03-26-2012, 02:11 PM

Mine will be gutted soon due to rattling noise under boost.

MA2010SS · 03-26-2012, 02:38 PM

No cats here, if you can get the rear O2's tuned out, and as long as they don't do a visual that's the route I would go...don't know what the regualtions are in Canada regarding this

Caswell239 · 03-26-2012, 02:54 PM

That's what I figured. I heard of people melting cats on just the 2.3 Maggie making less power.

Meister@Torq · 03-26-2012, 03:10 PM

These catalysts are simply not designed to take the excess heat and richer mixtures. We have not had a single failure yet with a Camaro and make 660+RWHP on stock engine setups.

If you want a 100% guarantee, no cats is the way to go

I don't mean to be a d*ck, but i think you just contradicted yourself there.

Imo no cats is the way to go. Lower boost pressure and no chance to melt/blow them out.

10aSSee D · 03-26-2012, 06:07 PM

I don't have them either and don't plan on getting them...

jay@redline-motorsports · 04-10-2012, 10:08 AM

it all depends on the quality of the cats, most header manf. use a low cell count cat, those will melt. seen it plenty of times, down on power filling catchcans ect. high quality cats will not have a issue but they wont come with your long tubes.

I've been off the boards for quite a while. I actually had the first Whipple installed on a Camaro. I have a cam and Kook's LT headers. I'm at over 650 rwhp. I have cats. Why is everyone getting rid of their cats? If the cats break down, what's the danger?

Heat and no place for the heat to go if the cats break down, sounds like you have good cats on your car though

bluetorp · 04-10-2012, 11:04 PM

ARH high flows at... almost 10k miles now. Had them off last week. Pristine.

Standard Whipple kit, plus ARH LTs/cats and custom tune. Around 550 on a Mustang dyno last time it hit the rollers.

BLACK10 · 04-10-2012, 11:24 PM

I have the kooks cats on my car and im at 745rwhp. Took my exhaust off recently and the cats still looked new. About 4k miles boosted on them

FloMoCamaro · 04-11-2012, 09:34 PM

I run gutted cats - 739rwhp (18 lbs of boost) - I've seen the inside of the cat shoved down the pipe on much less boost and hp.
