Are you going with a 3" system? What kind of coating? Sounds expensive lol. I also bought the xr1s whenever I was getting my catback built but they the bastards didn't use them. Instead they gave them back and charged me for some dynatech mufflers lol wtf.
haha, i totally feel your pain! I gave them 150.00 XR1 stainless ballar ass mufflers that were completely blow-through style. they didnt fit, so they slapped some Jone's Exhaust chambered aluminum blah blah on there that cost $41.00 each. . .. -_- I mean, couldn't they see the quality I was striving for?? lol.
and yes, its 3" from collector to tip.
as for the coating:
on the headers it has ceramic coating inside and out.
on the catted x pipe it will have ceramic outside, none inside.
on the catback it will have ceramic inside, shiny powder-coat on the outside.
and the reason I'm doing it is because its surprisingly cheep. lol. like $30.00/part. 3 parts (x pipe, two peices to the cat back_ =$90.00 ... why not? :-D
what length XR1s did you get? i figure if i dont like this jone's stuff I'll find some shorter XR1s and use 'em.
