Hey I need some advice. I have a 98 GT that already has the full PI head and typhoon manifold swap and larger cams. Im looking for more of an aggressive sound and a friend of mine has his 98 dumped and it sounds amazing and he doesnt even have headers and I have long tubes. What do yall think?

 

I run dumps with FRPP shorties and bassani catted X. It's much louder inside the car than a rear exit setup and kinda smells when you get in bumper to bumper sitting still traffic but it sounds badass outside the car. I would advise against doing it with flowmasters though... that combo rattled my nuts at 1800rpm. Magnaflow or Borla or bassani make great sound.

 

i've dumped my flows, and macs.. and they both sound so much better than rear exit.. but the flows rattle everything like crazy in the drone zone, the macs to but not as much!

but thats the way to go...

 

I've thought about going with dumps on my car just to see how much of a sound difference there is. I figured if I didn't like it then I could just get the pipes welded back on. I would also have to get a V6 bumper though.

 

sweetness thanks guys.

 

flowmaster 1 chamber race series dumps here. I love the sound and so does the wife but if you ever have to carry kids I wouldnt advise it. At certain rpms its EXTREMLY loud

 

i have a 98 4.6 with stock manifolds no cats and dumped super 40s, i love the sound and get compliments all the time but it does vibrate alot at lower rpms

 

If the question is dumps or no dumps, always choose dumps

 

get electronic cut outs best bet loud and quiet when ever you want

 

I heard if you run dumps and angle the turn downs inward it will help with some of the noise, by canceling out the drown.

 

definately dump it! you wont regret it. my 96 cobra with bbk o/r h and flowmasters sounds awesome. i dont have turndowns on right now but am going to and mine dont rattle the car that much anyway not enough to care. so go for it

 

No you angle them outwards a bit to help get the exhaust fumes away from the car and lowers the sound a bit too.
