Just my opinion.
When you took yours off, did you look at it and compare it to the gp downpipe. Are you saying it because the diamteter is bigger or because of the fact of no u bend? Because i am thinking of going power log and rockers, but if i do the rear then i have to do a dp because of the 1995 thing. I would like to see a picture of the gp vs the bonneville dp.
I've dropped my friends w-body (regal) exhaust so I have seen both. Basically the w-body DP curves down in a hurry because the firewall is closer. So the bends are more abrupt.
Don't just get the power log. ZZP dynoed with just the front and they had to add more fuel only to the front bank to make it work right. There is no way your going to be able to do that with any pre OBD2 pcm. I had a rear mani for you a while back but have since given it to a friend for his turbo project. Get another j-yarder to get one for you if you can't find one.

so it is a good idea to get just a regular ported front for now and then do a ported rear when i come across a 1995 one? Do you think i can get away with 1.84 rockers on a stock downpipe and a ported front?

Sounds like an exhaust shop got to your exhaust system and installed a new cat. And those were the only pictures I had.

It'* kind of a Joke as to where I plan to go with modding my N/A Check date too, this is an old thread


And I personally have schooled a SHO with an SSEi, but I'm going to stop here with this post. Like I said it'* old, and this is off topic.
