RE: No-Cat's & Exhaust Smell

PDQ GTO · 04-23-2008, 06:53 PM

I have a SLP's LT's & LMI exhaust and no Cats. Seems to smell a little rich from time to time and I am wondering if she is truly running rich, or it's beacuse there are not Cats. filtering out the fumes? Any thoughts or advice would be most helpful. Maybe she just needs a re-tune?..

Thanks,
Rich

i have the slp and highflow cats. and it smells rich to me. i got the diablo tune by slp and did the 455 tune wich turns off the o2 sensors. that helped a bit. i think maybe i'll get a dyno tune soon

Yup, im running catless and have been for a few months. Definitely smells pig rich, but i think that is just from the cats no longer filtering the fumes. I was dyno tuned before the cats were removed and hope to get re-tuned next month. But i am expecting not to be running much richer then before.

Ok fellows.... i have to ask. How loud is it really? I have resonators and SF h0pipe and going to order catless longtubes this weekend. I think i can deal with the smell, but are we talkin cant hear music in the car, or set off car alarms revving nxt to cars ( which would be bada**). But what are we sounding like here?

Blow your ass out loud!!! Anything more than a 1/2 hour in the car and your ear's ring. On the freeway the drone is over the top, the stero will help if it's at 63... I like the sound, but I am not in my Goat all that long at any given time. Alarms get set-off and folks are always turning to look at the bully coming down the road...This has been my experience-FYI...

BTW I also have a semi radical cam so that makes it all the more rude...
The best system I think, forking mind-blowing. I love SLP stuff, loud in your face FO LT's!!!

Stock cam, no cats, straight pipe back to 2 Thrush Glass packs! It gets loudy after 2500-3000 rpms. 75mph in 6 gear, the radio covers it up nicely. This will give you an idea.
Click here I wouldnt change it for the world!! Now when i do a cam and headers, this may change..
