For my Mach 1, I already have an SLP LM1 catback system...
I'm looking for headers, and e-mailed Fasttoys to see how much their MAC Sale is...they replied with:
Mac part # TF9625 long tubes: 275.00[/align] Mac part # PC4900 Dura Black coated prochamber: 205.00

Cheap?
Fitment with SLP LM1s?
Buy it?

PC have cats? i assume it doesn't and that is a good price for the O/R PC also good for the headers but i would still go BBK LT

 

I've seen them for $359.99 for the LT's. So that's a good deal. Gotta remember though, that's HTS coated. Ceramic is better. The HTS is prone to flaking.
The Prochamber isn't bad, not as big of a discount and the lt's. $259.99 for the prochamber.

$619.82 versus $408.00 Depends on how good shipping is. But even if it's $50.00 which it shouldn't be, that's a great deal.

 

yeah I originally intended on going with all SLP (midpipe and headers to add to the LM1s)
But for headers alone you're talking $800 at least
That's why I am considering this purchase...

 

and for the headers, what is the difference with 3/4 and 5/8...which would be the best option for LM1 setup currently and combined with the prochamber on a Mach 1?
