Just installed mac's new exhaust on the lightning. Took me about 45 minutes without a lift. Fit is excellent and sounds bad azz! For the money you cant beat it. Nice big shinny tips to. I would reccomend this kit to anyone.

 

Damnnn, youre running 16 PSI through that stock block? How many miles do you have on that combo?

 

He should be running way more than 16 Lb's. Mine was running 9 stock, up to 12 with just a hi flow ram air filter, then with the Upper Pulley, Chip, and By-Pass it took me to every bit of 13-15 Lb's of Boost. My guess is he's up around 20+.

 

Where are you getting these reading? If its the stock gauge, they are somewhat optimistic in its reading

 

Hey, did you make sure you tightened the bolts. These exhausts are known to fall off when you install them half drunk at 3 in the morning.

 

wantalightningHmmmm where did u get that info? Sounds like you were at my house during the install...... I wonder who you are lol

8 Pound lower and stock upper I dont have a aftermarket gauge so dont know. But yes it is the stock bottom end. 18k Everything will be fine. ( knock on wood)

 

i have # 8 lower and a # 2 upper on my 99 and it is stock also.
mine shows about 17 pds of boost on the gauge. i think the upper may be good for about 1 pound.

 

lightning00n93cobra,

Where did you get your kit from and for how much?

 

I got my kit from JL. It was 300$.

 

you might think that but do you realize that a 8lb lower is much larger then a stock lower that the 2lb upper is rated for?


So you running about a 4 to 5 lb upper with that larger of a lower pulley.
