Exhaust

[jdbubb at ix.netcom.com (Dan Bubb)]

You might as well pop for a 2.25" exhaust. Not much more expensive and will support any kind of
normally aspirated (NA) performance improvements you may do in the future.
The 2.5" is really only for extreme NA applications or forced induction.
Get a CAT that's the same size as the exhaust.
Dual downpipe setups will mate directly to the 2.0 and 2.25" systems with a 3 bolt flange in an 8V.
2.5" is a slip fit, so applicable to 16V NA of turbo type stuff where you build your own to fit.
Stock pipe size is under 2.0" IIRC so any of these are an upgrade.

Going to replace the exhaust under an 85 8v. I was looking online for some exhausts and I need to
change the cat too as the flanges on the ends have rotted beyond repair. They are showing a few
different size cats when I look under MKI. Looks like 2", 2.25", and 2.5" diameters. It's been a
while since I have messed with exhaust on that car, so I don't remember what the stock diameter is?
Don't want to buy one of these and have it not fit. Also if I was going to change over to a dual
downpipe setup, as I know I should for obvious reasons, would I have to go with a larger than stock
pipe?

Thanks,
Chris
