stock h-pipe and no muffs....that's my solution for the best bang for your buck exhaust ;)

i wonder if i got a new catback setup.. hmmmmmmmmmm. it just sounds SO beater when it happens, i have to figure this out.

That would probably work, the shape of the flowmasters lends well to raw fuel sitting in puddles in them.
You've checked your timing first though? How many miles on your car? Worn timing chain can cause it to backfire as well but by the time there is enough slack to make it backfire, the car will usually feel really lazy.
I'm also a fan of the speed density system, I wouldn't swap it out unless you are going to do a cam. Even then, I'd consider having a chip burned on a chassis dyno to make it idle properly rather than go to mass air. The Mass air system is good for adaptation, but the speed density cars run harder.

red82 is exactly right, and IMO Mass Air cars aren't really that more adaptable than Speed Density, if you change injectors you have to have the MAF calibrated for it :rolleyes:

There are some great sounding and performing cat-backs around.
:tup

I dont think your problem stems from running Flowmasters, thats the most ridiculous thing I have ever heard (no offense). I've had Flowmasters on many of my cars and I've only had the backfiring issue on my best friends '95 when we switched to an off road h pipe and only on a hard downshift. That was fixed when I installed a pair of new 02 Sensors. I've even had a speed density vert that ran great with a K+N, B-cam, shorty headers, off road H pipe and Flowmasters and the car never backfired.
By backfire are you talking about a loud POP or a series of pop-pop-pop sounds?

it seems that after i put a new spout connector on, it corrected the issue. or it hasn't happened in a long time since then, and its just a fluke. you ran a cam on a SD car and didnt reprogram the computer?? most people make out the SD cars to be so finnicky if you don't convert, but since talking on here it seems you can do almost anything without mass air.

Well, to be totally honest with you its hit and miss sometimes. I've run several cams in SD cars without any problems, and a few others wouldnt even idle. The B cam seems to work well with SD because it has 114* of lobe separation. Not my fav cam, as I hate all letter cams but it works. Crower makes some fantastic cams, I believe one is a 51110 or something with about .480" lift, 220* duration and 114 LS. Works without flycutting the pistons (87-95) and performs great even with stock heads, obviously works great with some more work and usually you can get away with keeping the stock SD comp. You can do alot to your car without having to switch to MAF or even getting a chip burnt.

thats good to know, because wasting money on mass air when i don't have to, sounds like a crappy idea. for that money i can throw in some 410's. it would be awesome if someone had some sort of database on what components work well with SD cars and which don't :D. I'm sure many people (like you) have that knowledge in their head, but it would be great to have a list, maybe I'll look around the net.

i've never come across anything like that, it just takes some experience....knowing what others have done, what's worked and what hasn't. you've also gotta be a little picky about what advice you do take and what you don't. personally i'd rather assume something will work if someone says "yeah, i did it on mine....here it is", that the advice of someone who says "oh yeah, you just can't do that to them"....seems obvious when i put it like that lol
