BuffGTO, thank you for the review. I'm trying to get the powers that be to make a reviews section of the forums. I think the reviews that people write are VERY helpful to others who are considering different products. I'm sure your post will help steer someone in the right direction. Now if we could just get EVERYONE to write a review on EVERY part they install...
BTW, let me know if that is the case.....I will write a much better and more formal one......this was just a 1-2-3
I just had my local muff shop put 2 flowmaster 40 series mufflers , they also took out the pre-muffler and put a x pipe into it sound nice under acceleration but back sputters loud when i'm down shifting, I don't like it. can anybody recommend a good cat back? what about headers what do you guys think?
That's a fairly normal sound on deceleration. Personally, I like it. If you don't though, you're stuck with stock for the most part, or something else which is quiet enough that you don't hear it. It happens with the stock exhaust too, it's just not as noticeable as it is with aftermarket mufflers or exhaust systems. There is a listing of various sounds of the aftermarket mufflers and exhaust systems here on the site, which allows you to hear what each one sounds like.
If you decide you want to sell the flowmasters and x-pipe, let me know, I may be interested in buying it, I've been wanting something a bit louder and haven't had time to go look for one myself.
Oh, and headers will further emphasize the popping sound, so if you really don't like it, you may want to steer clear of headers completely.

could your perchance tell me how to find that listing on here? i'd sure appreciate it.
The popping condition with aftermarket exhaust and or headers, is caused by running lean.
Aftermarket exhaust and or headers creates an increase in flow, which increases horsepower and request more fuel.
I had the same situation in my Bonneville when I opened up intake and exhaust breathing, the Dyno with gas analizer showed a 16:1 fuel ratio, which is very lean (ideal ratio is between 12 to 13 to 1).
The question here is who can adjust the CPU with the right fuel/air ratios?
I know exactly what sound you are looking for yellowgoat1. I finally just got it on mine...only regret is that I did not do it 10,000 miles ago! Put on the X pipe and take off the mufflers and go with straight pipes. Sounds throaty and deep, no drone on hwy, and not too loud overall. Sounds a lot like the mustang, but better to me.

Are you sure it is from running lean?? I just sold a dodge srt-4 with a CTI 3" turboback exhaust and that thing popped tons (in a very good way). All of the srt-4s (and many other turbo cars) do it and it is supposed to be from running rich.
