Anyone else get a cel with a supercat? |
No CEL here.
|
Had mine on for 3 months and a few thousand miles....and no CELs
|
i get 110 (underestimating) roughly for half a tank. =p
i go half and half highway city miles so yea =x |
has anyone tried this combo (ie. RP Supercat and cat-back exhaust) with a aftermarket header?? Will this be WAY TOO LOUD? Or just a major lose of back-pressure and low rpm power?

I installed mine yesterday, it only took 45mins. i still have stock exhuast but damn it sounds nice and u can feel it pull up high. my only prob is that at low rpm's and when its cooled it sounds alittle too much like rice
|
The ricey rasp should go away for the most part once it's broken in. You may still have some rasp when its cold, but after a few miles and its warmed up it will go away.
|
thanks man, aslo dew u think the dealership will say ne thing when i take it in

O.K. I just read through this thread and am contemplating a high flow cat. I have the MS exhaust currently. So here goes the questions again...
1. How loud would the supercat be with the MS exhaust? 2. How much power would the cat add alone? 3. Should I be concerned about clearance issues if I had the MS suspension? 4. CEL concerns? |
I would recommend a resonated high flow cat with the MS exhaust. Unless you like hearing the exhaust rip all the time. ;)
Shouldn't get a CEL till it clogs up. :sad: Power: you will lose some torque in the low end of the RPM range but will gain in the higher (over 4k). |
you shouldn't lose any low end torque on a zero overlap Renesis engine regardless of how big/free-flowing the exhaust is i.e. Turbo XS exhaust, if you do it's because of some other dynamic issue
bigger is better on this engine, unfortunately it's also louder too |
That is what I have seen first hand on my car and I have swapped back and forth a handful of times. :dunno:

we need an expansion chamber:)!

Thanks for the info! I am still torn between doing it or not doing it. I may just wait for the Cobb tuner first, then do the Hi Flow last....

I think he's referring to my custom exhaust manifold, which is not really an expansion chamber, it's really more of an old-style megaphone header
|
Bingo.
