I installed my own ring and pinion, 7 hours or so?
I'd like to see a video of someone doing the job in an hour. They can't possibly be making all the measurements.
Don't listen to all the haters above. I picked up about 10-15 Horsepower by using one of these on my Mustang. I'm a firm believer in the product.
I have one on order for the Viper, I'm really hoping for 45HP or more gains.
BUY IT.
;)
Actually, this video is possibly making me reconsider Xpipe / SLP kit on my car.
It sounds good in revs, but is that a stock engine sound at idle? How different will it sound on a stock engine?
I fit 285 on my 10.5... just about flush, not too much rim protection. Could fit even a 275 on there though.
295 on a 9 inch rim wont fit great, but it would probably fit.
What does tirerack say?
