I have flowmaster mufflers on my 2000 Lightning. The truck performs great, but I notice that if I am going above 45 miles/hour, and I let off the gas, I get a "gurgling" noise (back pressure??). Does anyone else have this problem? I find it a bit iritating. Thanks for any help.

 

That's normal actually, even the stock exhaust does it noticeably as well, and a performance exhaust is only going to make it that much more noticeable.

 

God I love that sound. The catback only adds to it

brrrraaaapppp vvvv blug vvvvv blug blug blug

Haha.

Ok so maybe it's not a "blug" so much as a "puhp"

 

ive been told thats good,means
the engine has compression.

 

A chip will really add to the backfire as it advances your timing curve significantly.

 

Please e-mail me for Toronto area Lightning Owners info. hayman12@attcanada.ca Are you interested in swaping rims?My 01'/02's for your 99'/00' style?

 

I was wondering if all other lightnings made that noise when you let off the gas at high revs..Wonder how cool it sounds to the person you're cruising next to...To me it sounds like Bass from a box with woofers BOOM BOOM BOOM bah BOOM BOOM I love that sound

 

It just gives me another reason to put the pedal to the floor!
