Main catalytic convertor help...
My 22 year old cat is buzzing to the point of annoyance now and pinpointed this is the noise source, not the many heat shields. Due to it's "pancake" form with heatshield above, it looks like the universal round ones might be problematic as far as fit. Anyone have the dimensions/source for a replacement cat that can fit in this space without removing the shield or worrying about the drive shaft clearance ? Don't want to just replace with a straight pipe. Any flat cats like the OEM on the market ?
Thanks in advance...

MAGNAFLOW 94007
Never a fitment or clearance problem. Heat shield can remain. Sxvfiles has done this setup numerous times , including my 92 and 96.

Re: Main catalytic convertor help...
Just noticed I am an idiot..it is the distal resonator, not the cat in front of it, that was the "buzzinator". Same question but different part needed..a "flat" resonator if they exixt. Sorry for my confusion.

Hope this helps...it's the way I'm going for around $65.00 total cost and being able to connect without welding which I have the capability of doing myself..Svxcess's system, per him, is solid with these excellent band claps and it gives you the ability to remove at least the posterior part of the exhaust w/o unbolting the whole setup. BTW, SVXcess..sent you a PM...

Re: Main catalytic convertor help...
The straight pipe is worse. You will get an annoying resonance (droning) at highway speeds. You need room for the exhaust gases to expand after exiting the converter.
Do a search here. The AR25's are a good bet. Ask svxfiles, who has done more SVX exhaust systems than anyone. .

They do not work well on OBDII cars; the system is more sensitive and needed pre-cats to keep the CEL off. After these photos were taken, I removed the resonators and replaced them with small Magnaflow converters. No problems since. Magnaflow 99204HM  .

Re: Main catalytic convertor help...
In an OBDI car is it ok to remove the pre-cats all together or do they need to have something else put in place?
