Need to make a decision...cat or no cat? Factory exhaust is in great shape, but the ceramic bits started falling out, so I'll need to do something (eventually).

Opinions? Parts recos?

Thanks in advance.

 

 

cat!

 

 

 

cat bypass and chip provides substantial power increase

but the fumes are strong, at start, and standing

not for the faint of heart (nor acceptable with spouses/kids or any one other than off-the-chain car nerds)

 

 

Thanks everyone.
I think I have my answer for now.

 

Keep the cat. The power gain - little as it is - in no way justifies the additional pollution.

 

Any thoughts on aftermarket?
Fabspeed has their sport cat...any experience?

 

 

 

No cat, primary bypass, Wong chip, done. Sounds great, pulls harder. I dont know what people are talking about in regards to a different smell. As for pollution, hardly anyone is driving their vintage collector vehicle that is often kept in pristine running condition enough to worry about the pollution aspect.

 

That's because they are using HJS cats, the best in the business. Little to no measurable hp would be compromised.

I have the FVD sport cat along with Steve Wong chip and don't notice any less power over the cat bypass + chip. If there's a difference, my butt dyno can't pick it up.
Only difference now is my son/wife don't get headaches driving in the car with me.
