Currently 06 GT w/totally stock exhaust. I can't afford to do the entire exhaust at once so I was thinking of just getting the boomtubes by themselves first. Couple questions.

Will I get any annoying pops or crackles with this setup? How much louder inside and outside the car will this be?

 

no loud pops or crackles....just low pitched grumble and rumble. it's much louder outside and a decent bit louder inside.....very manageable though. you'll love 'em

 

If you plan on doing the whole exhaust, i would get something different. Maybe corsa's,stingers, magnaflows? JMO. I ran my slps for a couple of months, but now that im doing the headers and o/r h, i have to switch the a/b's and lose some money. JMO.

 

Excellent that sounds like what I'm looking for.

I have a JLT2 plus tune coming from brenspeed. Do I need an adjustment in the tune just for an axle back?

 

I wanted a meaner sounding exhaust and didn't want to spend much. I'm very happy with my Boomtubes. They are loud but if you are cruising it calms down nicely so you can hear your tunes. A couple times when the car was cold and I reved it up and it did pop a little but only when standing still. Take off and it just growls.

Here is my sound clip and there was no popping. I used my digital still camera in movie mode so its not the best. Its really more mellow and bassy than the recording.

Get boomtubes. I love them. No pops or crackles. Here are my videos of the car inside and out with nothing but boomtubes

Thanks. Just want to make sure though. Will my tune need to be redone if I add boomtubes?

 

No tune adjustment needed for axlebacks.
