I am debating weather or not I want to get a cat delete pipe. Currently I am planning on a 3 inch exhaust and downpipe but I have heard that the cat delete pipes yield almost no power gains and on top of that can make your car run very crappy. Is it worth paying around $150 for a cat delete pipe or should I just stick with my stock cat and go with a 3 inch cat back and downpipe? Anyone got a cat delete and care to comment on how they like it or dislike it?

Thanks
Chris

 

I suppose it should give you a big gain right? From what i heard, the stock cat is very restrictive.

 

No from what I hear the stock cat is very high flowing unlike other DSM models. I have heard there is hardly any difference in removing the cat at all but I would like to hear more peoples thoughts.

 

just take the stock off and you will be like holy sh*t this thing is heavy, pick up the 3" cat delete, and its not 150 more like 75, and just smile. Its worth it except I can smell it sometimes.

 

I have an Hks downpipe with A Hks hi power cat back. I still have the stock cat will it hold back on performance, or should I get the cat delete?

 

Yeah, with cat delete you do feel more power, but many times I almost put my stock one back because of the damn smell. I tried not installing the O2 simulator, but my CEL came on. After that, I installed it, works fine now. I'm at 50/50 with the cat delete.

 

i have the hks ti and i felt a bigger gain by taking the cat out, than when i put the exhaust one.
i say go for it

 

I thought I read on here removing the Cat yielded ~ 5WHP? Personally, FOR ME, it seems silly to have your car smell like crap, make everyone else breathe it in and possibly getting a hefty fine (I hear $10,000 in Califirnia) for that small of a gain. Another option is to go for a High Flow Cat, which yields nearly the same gains of going catless. Search for Silver Surfer's posts as he did some tests awhile back. In the end its your call though, so good luck!

 

Go for a 3" high-flow cat. It should be less restrictive than stock, give you gains close to a delete pipe, not stink, and not throw a CEL.

 

I had a cat delete on for about 2 days... the smell was just too much. I just didn't want all the people who are driving behind me to be in that much pain as I was standing behind the car. I say stay with the stock cat or a high flow. Probably just stock cat, can't be more than a 5hp difference between stock and highflow.

 

Go cat delete, I did and I love the power gain.

Ultimate Racing 3" delete pipe gauranteed not to throw a cel, no cel for about 2 months now, car is smoother, more power and doesn't seem hesitant from a low rpm take off now.

 

I have installed the Buschur delete pipe with thier kit. Noticed immediate improvement up top. I will though add a Random Technology high flow this coming week for emmisions.

 

you guys are worried about what other people smell??? maybe eventually the smell will go away?? my car stunk when it was brand new.

 

i have 3" turboback no cat and cut off resonator on JIC catback and put 3" pipe there, no smell, lotts of power, but cell light is on, i love it!
