my exhaust pops under decel, is this normal?
So as of late my car as been sounding a little different, and acting a little different, I'm gonna list all the work I've done up until the point where I start to notice all of these things, and by these I mean 2 things
1 Short Ram Intake
2 A3 Deep Tone Racing Muffler
3 Fuel Filter
4 SeaFoam
5 Changed Both Valve Cover Gaskets
That's pretty much it, so these are what I've come to notice with my can.
1 When I'm on the highway going about 50 and above I'd say because I've never really test this... when I let up off the gas I can hear the Muffler making a rumbling sound, or a popping sound if I may it's not that loud, but without music playing I can hear it clearly until the car slows down.
2 when ever I am on the highway driving, or anywhere for that matter if I'm going fast an I let up off the gas I can feel the car rank back, but most of the time I'm not going fast I could be driving at a high speed then let up off the gas then I would feel the car drop back a little not hard, but I can feel it

Who is this guy to tell me what to put on my car... if I left something out on my post then ask for the information if you wish to answer the question, but don't jump into the conversation as if it was pointed at you, that was rude, and you should have more respect.

Also man no one is tryin to tell u what u can and cant do .. Its your car do as u please, were all just trying to give our input to help u out man, hes just giving his advice on how to help out ur problem. I mean u posted to get feedback to help. The 4th gen forum has some people that really know there stuff

It wasn't a help me topic, I just wanted to know if it was a normal thing, I don't have a check engine light, and I knew one of them as to be the cause, asking for help is me being lazy, I could simply undo what I did if that was the case, didn't mean to hurt anyone's feelings, but some of these guys have a thing for being a **** when it comes to helping others, they'll more likely insult your intelligence, before they take a crack at the question or help someone

Don't just put question in the title. Put a little more into it like "my car (or exhaust) pops under decel, is this normal, please help quick question" and the reason he said to put the stock intake back on if you're auto is because of previous tests people have done and found what works "best". I just put on an aem dy-flo cone filter on an aluminum maf adapter and a warpspeed fed spec y-pipe with magnaflow hi-flo cat and apexi world speed cat-back with additional resonator and it pops too. I usually have it in neutral though because the car is old ('97se 5spd daily driver) and I'm still fixing things so I don't want to stress it anymore than I have to, I save that for when I want to rip it. But last night I was dropping off a friend and when I crawled to stop in second I believe it was, it poped and gargled, so nice!

You could, but then you would lose any possible entertainment value.

Please be more descriptive with your thread title next time. Think of it this way. If every thread was titled "question" or something lame or vague, when someone did a search, they would have to sift through a hell of lot more threads to find the answer than if the thread title was more descriptive. Who knows, maybe someone will have the same or similar question as you some day!
You can probably see a pattern, that the users who care and who have been on here a while, usually have very clear thread titles. That's one of the reasons why I make my thread titles so descriptive. I'm hoping to help out the next guy using the search function, and not be selfish and just worry about getting my question answered at the moment. Pay it forward people!

My car sounds and drives better so ima leave it on, the only thing I notice is I use more gas but that could be due to my new fuel filter that's allowing more gas to flow or my new racing muffler, but I don't have a problem buying gas, I want my car to sound, drive and look how I want it to, gas mileage isn't gonna change that

Kind of ironic to post a rant asking bashing rants haha, but I made a statement because we don't know his question. He got a reply and came back with an angry comment, but he had no question in the original post so the reply he got was what njmaxseltd assumed was the question he wanted to ask.

put the stock intake back in
The auto keeps the RPM's down low, and for whatever "true" reason cone intakes under the hood (also know as HAI or hot air intake) seem to bog the VQ under normal driving conditions. (Lower RPM's less air flow through the motor)
The facts are simple and well documented on here. The stock intake gives the auto the snappiest throttle response. The cones do nothing more then make noise and reduce the fun loving VQs throttle response.

It's well documented on here that auto's don't respond well to short rams and cones. They do OK with a true cold air setup. Place Racing was a favorite. The reason is the 5 speed revs higher, pumps more air through the motor.

My car response very well, and even better when I changed that clogged up fuel filter a few weeks ago, I wonder how my engine would get fuel as fast as I wanted it to if gas was playing stop an go thew the filter, now my fuel flows so, and my muffler adds to that to make it perfect

Cold air is denser with more oxygen content= more torque. Cones draw hot air off the engine and you lose power. The stock intake IS a CAI and works better than all current "CAI" setups.
Stock intake is narrower with higher velocity and this also makes more torque than a large bore HAI at stock rpm levels.
Your butt dyno and perception is not equal to dyno runs already done to prove this very topic.
If you are backfiring on decel you are too lean, probably a vacuum leak resulting from the vc gasket job.
/fail thread.

I always rub my hand along the line of the gasket close to the firewall (yeah my hand fits) I wiped it clean before after I did the Change of Gaskets, Then I'm always checking it for oil leak, nothing comes up, and i can pretty much see around the rest of it, I just recheck all the hose, and nothing... everything is on, No I didn't use a new plenum gasket because I didn't think I need one, Ill have to check that out next...
