I have been planning to replace the aging stock exhaust on my 1989 Turbo with a BIC DDP with recirculation, the Random Technology high flow metal substrate catalytic convertor (Model #141-30033) and the HKS Turbo Exhaust (LET-T16).
I was about to purchase the cat and cat back exhaust when a co-worker warned me of the failings of high flow models. He stated that the smell of gas, especially in the garage, is a problem and that high flow cats have to get extremely hot before they become effective, making the car a worse source of pollution over all.
So I was just curious as to how people with the Random Technology models have found life with these cats?
(Are there smell of fuel/gas issues? Do you fail emissions with an otherwise smooth running car?, Is reliability a concern?, Do you recommend another brand?, etc.)
Also, please no arguing about test pipes versus cats. I will have one on my car as I don't wish to be a further burden on those behind me or the environment.
Apologies for yet another cat related thread, but after reading everything I could find here and elsewhere I couldn't find all the information I was looking for.
Thanks in advance for all comments and insight!
