Cat vs. Cat Bypass
 

Last night I returned my cat converter to it's rightful place on the car. Did this for two reasons. First, with the 2 out Flowmaster, it was just too damn loud. Second, I'm packing my toys for a move to Seattle and will have to get it inspected when I get there.

I installed the bypass a few months ago and thought I noticed a seat of the panties difference in the cars' power. I wasn't sure, because I thought the additional volume may have deceived me to think it had more juice. After reinstalling the cat last night, I can tell a significant drop in power. Enough so I thought something was wrong with the car at first.

Good news is that WA smogs car up to 25 years old, and because Red is a 79, this will be the last test. Sounds to me like it's about time for a set of SSI's!!

When I installed my "test pipe" a few months ago I felt an improvment also. Not much, just a little bit. I was informed by some "experts" that it was all in my head but I didn't buy that.
I'm glad to hear that someone else has the same impression.

You're going to like the SSI system. You're also going to like your W WA experience, particularly the terrific pelicanheads in our area.

I don't think it was in your head. It's an old cat w/ a lot of miles on it. Installing the bypass is probably what a new cat would feel like. Last test, go for the SSI!

That's one of the things that will mak the transition much easier. Even though I've only met a couple of Pelicans from the PNW, I feel like there is a a community that I'll fit in to pretty well - That is, if ya'll don't mind me saying ya'll..........

After I get there and settle in, I want to drop the engine to fix some oil leaks, clean up engine bay, do SSI's, maybe a set of 20/21's, backdate the heat, and have JW rebuild the tranny. After that, on to suspension!!! Anybody wanna come get greasy?

Absolutely!!! Us PNW guys do love our engine drop parties...although there is probably more beer drinking and lie tellin' than real work going on...

If you don't do the SSIs, then there's also the premuffler... I found a much more noticeable improvement than the cat bypass.

Now das what I'm talkin about!

Hey Mark- That is good info. I don't think I've seen a reverse "Butt Dyno" report on this before! I hope all goes well with the move. Will we see you @ the Pelican meet in a couple of weeks?

Hey Ed,
I'm absolutely planning to come. This may be my last get together in Dallas. I'm working a contract on the house that should close 9/5 if all works out. When that happens, I'm off on a road trip. Unfortunately it will be in the pickup instead of the pcar. Oh well.......
