Can a clogged cat do this?

[Need4Camaro]

Make your car bog down so bad that WOT is no different from Half Gas? I pulled out of an intersection and gave it half gas and the RPMS were just slowly rising, then I punched it... absolutely NO difference in accelleration it just continued to slowly rise as if I had never surpassed half gas... It feels like I lost 50 - 90 HP sometimes and othertimes it's fine but still not quite as peppy as it should be. Like from a stop I can floor it, No wheel spin, I can't burnout, The RPMS just jump to 1.5 then rise up from there, it's not ENTIRE irresponsive it still does suck you in and launch just nowere near as peppy...

Details are...
155K on the clock
Stock Exhaust and Cat
CAI

I don't smell anything and I have no SES codes... but know when I really notice it bog down?... Right before it's about to rain... Even the engine sounds different, not like it's missing or anything, but more null...

I recently ran seafoam through the brake booster, oil, and another bottle through the fuel tank. I've done my tuneup less than 6 months ago... I might switch to taylor wires and better ignition coils sometime within the future but I don't think that would be an issue this early in the ball game... I've done regular maintance on the car and until recently you really couldn't tell how old it was...

bang on your cat in the moring while it is cold, if your a rattling noise then it is your cat, that means the catylast has broken up and is plugging your exhaust. When mine broke I couldn't go past 2500 rpm, too much backpressure. Hey I just looked at your post, take your car to the dealer for a free factory replacement. The cat is covvered for 9 years after purchase. Cool its a 450$ factory part, good luck.

My car have rattling noise for about 2 month, it does it on the fist gear only.
When cat fails, it clogs exhaust? Awesome! Now, how would i get that stuff out?
Also Razzer, do you know if the dealer will perform the warranty if I had my muffler replaced w/3` WS6?
ps. I don’t have a SES light on. I taught that it would light up right away if cat fails.

You can ask if it is still covered, as long as the stock cat is there, they should cover it. check it out first to make sure. Take your vin to the shop and have them get the vechile history off of their computer,

[iGoRa]

Not covered. 8 years or 130000km. Too bad, I have already 160

The cat will bog your car down to an extent...sometimes it can be pretty bad, and causes operator to swear at the GT that just passed him.

Hey that's a nice exhaust you got on there what is it...(sarcastic)
