You should post some in cab videos or drive by's.

[Ja1meJr]

Did your truck have a resonator? Is it still on?

[chamisi]

did it lower egt did you put it where the cat was ?

[PowerThirstyPsyco]

I ordered mine. should be here tuesday. do u know what the sound difference would be if i got a 5" tip instead of a biggerone? would it be louder,higher pitched,quiter,ect??

[1dirtybum]

Sounds good. What size tip do you have?

[energinerbuzzy]

I think it's 7"

[PowerThirstyPsyco]

Hey how does it rate 1=stock and 10=straight pipe. I have the cat cut out also and want a 4040xl but it cant be too loud.

[energinerbuzzy]

Well since I have never straight piped it, it's hard to answer that. But I would say about an 8. There is no drone in the cab and once your up to highway speeds, it almost is quiet as stock. But put a load on it and driving around town at low RPM's is loud but not too loud.

[YFZRIDR91]

hows it sound in the cab?

[foolsonparade]

HOLY SHIT!!!
