I have an 05 GT and have changed my mind on installing Flows. I have an off-road x-pipe and was wondering if I installed the SLP Loudmouth system or the pypes muffler delete would that cause any damage to my engine. I have heard that if there was not enough backpressure that it could cause damage to the engine. Would having no cats and mufflers cause any damage? Has anyone done this before? Any input would be great.

Thanks,

if you put them on look for puffs of blue smoke comeing out the tailpipes

What about boom tubes? Are they the same as loudmouths?

O/R X plus loudmoths equals a load exhaust that sounds like crap. I don't think boomtubes would sound much better. O/R X would sound good with a canister type muffler such as Bassani Race, Stingers, Corsas or Magnapacks.

No you dont. You smell it, but no blue smoke...

I've never heard of the lack of backpressure hurting anything, but i have heard that when you go up hills it hurts power or something, im not sure if its true or why it would happen

Flowmaster 40's welded in the middle. That would sound sweet. That kind of setup already sounds good with cats but rather quiet. O/R should wake it up good.

i deleted my mufflers and it sounds amazing.. i still have my stock h pipe though so i got cats.. i can't imagine what it would sound like without cats and mufflers.. omg its so loud as it is right now

it won't hurt your engine.

That would mean you're burning oil. It has nothing to do with having no back-pressure.
