Exhaust Question
#1
My "83" has a RacingBeat header,cat,pre-silencer & muffler.About 2 weeks ago,it sounded like a pop can was rattlin' in the cat at low rpm's.The sweet tone of the exhaust went away & it started to sound like a stock system. I brought it to my local mechanic & he took a look inside to find that the cat had "fallen apart" on the inside(a VERY short life)...so he removed the excess debris & off I went, now even a bit louder than before this all happened.My question is; Am I hurting it or is it helping it? I was on the highway last night & it seems to have even more grunt than before...Thanks...love my 7...F1Ernie

It will sound a little louder and it will have a little more power because its lost some restriction from the cat now. About the only thing youre hurting is the o-zone layer because the cat is no longer doing anything. Come emissions time, youre most likely going to need to get a new one, but until then, have fun with your sweet sounding and powerful car .

yeah, you might need a new one when emission time (if you have it). i've got a rb system that the cat bolts off and a straight tube bolts on. i don't wiry about emissions though. just take the cat all the way off.

I think thats what Im gonna help my friend with his Prelude do. Hes gonna get a DC 4-2-1 header, then a high flow cat with custom flanges welded on so it can be unbolted, then an R&D cat-back system. That way, he can unbolt the highflow cat and bolt in a straight pipe during non-emission times, and only use the cat to pass emissions. It lasts longer that way anyway .
