For decades, I was all about getting new speed parts and bolt on speed. The last few years, I haven't been that way, but have been amazed at the loss and degradation of performance over time as common components age. Oftentimes it is like shocks...the effect is so gradual over time that you don't notice how bad they have gotten until you replace them with new ones. Same goes for a lot of engine components. Now more than ever I understand why when I was younger, everyone was telling me to get a solid baseline first before adding speed, it makes a big difference, especially on a twenty or thirty year old car.


Naturally, as with anything, it gets healthier and faster if you throw money at it...LOL

If you are passing CA's sniffer test then your convertor is likely still functioning well enough to pass, but a newer high flow cat (make sure it is CA compliant with numbers on it and welded on in a way that the smog guy can read it...believe it or not, both have been a major issue) flows so much better and is more efficient at the same time.

On my '95 and also the '90 that I used to have, both were running so well on the original ones that I thought it couldn't possibly make much difference, but I did it anyway. I was amazed at how much it helped...it just woke both of them up. Even the exhaust note was louder and healthier with the engine more willing to rev. Driveability was improved in all ranges and the car was a lot more fun to drive all around.

As always, each car is different, but in my case, it was some of the best money I spent performance-wise in a long time...definitely worthwhile. Two Magnaflow cats for the '95 was only $250 installed and the single cat for the '90 was even less. When it comes to cats and exhaust, I prefer a muffler shop to a mechanic since that is their forte.

Happy Saturday, all!!!

I agree all the way, a c4 gathering would be great, and I also agree about muffler shops over mech shops, that's why I'll be going to kent(mentioned above) at RPM mufflers in Hayward, this cat even fabricates his own exhaust components...has done all my exhaust needs for over 20 years. Great guy, great shop.

And SHOCKS! What I difference when I took off the 30 year old originals and put the KYB's (gas adjustable) on there. What an all around upgrade as far as the "ride" even got more miles per gal...and that's all ima do, that way the rest being stock is enough to accommodate the bit of performance it'll be receiving.....
