when i bought my 98 GT it already had flowmasters umm.. i think an h-pipe not to sure and all cats are removed..my exhaust was cut after the mufflers my tail pipes are still there, there just not welded to the mufflers if i were to weld the mufflers to the tail pipe would the sound change? bad or good? cause right now its really deep and loud

 

It will definitely change.

 

get a piece of pipe to aim the few inches of metal after the muffer DOWN. this is called a Dump. it makes the sound reverb off the ground and should magnify the sound you already have. Then just take those tips off and sell them to a v6 er.

 

So are you saying that there is a gap between the tailpipes and the mufflers? If so, than you are losing alot of power. Go get them things welded back together.

 

how do you figure he is losing power?

 

If he has a gap between the mufflers and tailpipes, like their not connecting and air is flowing out of them, he is gonna be losing power. Just like when I installed my o/r h-pipe, I only got it have way finished because I needed another tool and the shops were closed, so I drove around with a cap between my h-pipe and catback/tailpipes, whatever you wanna call it, and that car felt so damn sluggish and slow.

 

I dont think anything after the mufflers matters thats my personal oppinion. Tips dont create back pressure or reduce any flow that i could imagine. If the cut is before the muffers ok i can see that doing something but not after them.

 

I take it that is true. The tailpipes really cant create that much if any back pressure. I was thinking of taking off all my exhaust after the o/r h-pipe, would that reduce power? I know it would be loud.

 

I think it would sound like poop without mufflers. you may loose torque from it.

 

You will probably gain a little power and lose some tq. I dynoed mine with dumps, then put my stock tail pipes back on and dynoed again. I picked up almost 30 ft lbs of tq. Now granted, the tail pipes were stock so with the smaller diameter, some back pressure was created, therefor increasing tq.
