So I've had the car for about 9 days now, and I finally got it up on a lift. To my surprise I discovered that I already have spintech mufflers welded in. They sound good and deep, so I had the exhaust shop just remove my resonator and weld in straight pipes, while keeping the spintech mufflers. Deleting the resonator did add some depth, but I had no idea these mufflers were so quiet. It sounds good when revving, nice and deep, and no rasp, but it is not loud at all. I know if I add an x-pipe, it will probably get even quieter. I've heard tons of soundclips on youtube, and the spintechs sound pretty loud and awesome, but mine seem super quiet. Not sure what kind of spintechs they are, but they are rectangle in shape, and maybe 8 inches long by 6 inches high. they're pretty small. Are they normally that quiet? Even full throttle sounds somewhat quiet, and doesn't get loud until the car redlines and shifts (auto).

Spintech is usually one of the loudest mufflers you can go with. Idk why yours would be so quiet. But then again all i have heard are you tube clips myself. I had magnaflows and they were very quiet and didnt get very loud until redlining too. Are you SURE they are spintechs? Because iv never heard a quiet gto with spintechs.

Well heres the problem.
I'm assuming you're still catted and have stock manifolds..
Also, get an H pipe welded in.
What size pipe is used? 2.5" I'm assuming.
Which version are they. It should say something like "super pro streets" on the side.
Is it quiet inside the car (what you're hearing) or have you tried it outside?

also, to me, its super quiet in the car, I have not let anyone else drive it so that I could hear it, so maybe its louder outside. The deepness sets off alarms, but it isn't loud at all at least to me. I had a trans am with longtubes, ORY, and a powerstick, and my Lightning had an ORX and magnapacks. Both were loud as hell. I know I can't reach those levels without longtubes or a cat delete, but I think I can fart louder than these mufflers

they don't say super pro street, but after going through spintech's website, the only mufflers that match the size of the ones on my car are the Super prostreets. These things are super tiny, and spintechs website says that they are 4x6x9, any other muffler on their site is bigger. The ones on my car have to be those

i got a full spintech catback with headers on my car dude and i think it is super quiet but all of my friends tell me how loud my car is. i dont believe them but with so many people saying it they all cant be lying unless they all have it in for me haha. but if you go to the spintech website the mufflers that we have are designed for a quiet interior sound while having a loud exterior exhaust. so trust your friends im sure if you let someone drive it you will change your mind

Im running straight pipe and mines LOUD.. maybe that would be your answer.. cut those out and see how you feel.. everyone loves mine that hears it.. worst thing that can happen is you dont like it and u put the spintechs back on.. at least u would have piece of mind.. just 2 more pennies..

my mufflers im sure is right where yours are and maybe because they are so far back is why its not that loud inside the car, but my dad says he can hear me about a mile down the road when i leave the house and im not getting on it, rpm's are around 2. if you really want to find out how loud they are from the outside just let someone drive it down the road and back and see what you think and go from there.

Yeah bro, i had spintechs before the turbo projects, and they were def. loud as hell, of course my were mounted under the rear seats, (04') and dumped their as well.
They are also going back on as a street exhaust after my cut out, i miss them that much, Hands down the greatest sounding exhaust ever created!

Your other vehicles aren't insulated as well as the gto that's why it sounds quieter inside to you. Also your Trans am had longtubes. I have Magnaflows on my Silverado and Spintechs on my gto and in the cab the Silverado is louder but from the outside the gto is louder. I love my Spintechs and IMO they are one of the best sounding mufflers for the gto. I have the full catback with x-pipe and the xpipe gives it a nice crisp sound. Have a buddy drive it so you can hear it from the outside.
