joker81 Posted April 27, 2012 Share Posted April 27, 2012 Hi Guys, I've always liked the sound of Borla mufflers. I have a 72 240z that will be undergoing a swap shortly. L28ET engine is being worked on as we speak. I am trying to figure out what my exhaut system will. Trying to figure out what muffler is best. I'm confused by the description... http://www.borla.com/products/product_multi_detail.aspx?cat=2&type=43 what do you guys think? 1 Quote Link to comment Share on other sites More sharing options...
Leon Posted April 27, 2012 Share Posted April 27, 2012 There is no best. What are you confused about? Quote Link to comment Share on other sites More sharing options...
joker81 Posted April 27, 2012 Author Share Posted April 27, 2012 well there is 3 options... 1 - center/offset 2 - center/offset notched 3 - offset/offset 4 - Offset/Offset Notched i don't get it.... Quote Link to comment Share on other sites More sharing options...
Leon Posted April 27, 2012 Share Posted April 27, 2012 well there is 3 options... 1 - center/offset 2 - center/offset notched 3 - offset/offset 4 - Offset/Offset Notched i don't get it.... The photo in the link shows it pretty well. I believe people typically use a center-in, offset-out setup on the S30. Quote Link to comment Share on other sites More sharing options...

Leon Posted April 27, 2012 Share Posted April 27, 2012 yeah i mean that picture looks right...thanks for the imput. I'm talking about the picture that shows what center and offset mean: pipe inlet and outlet locations. Quote Link to comment Share on other sites More sharing options...
RebekahsZ Posted April 27, 2012 Share Posted April 27, 2012 I had a borla XR-1 2.5 in and out on my L24. I loved the sound of it. It is not quiet, but sounds just great. Mine was center in center out and it hung kind of low. The muffler case was 14" long and it crowded my tire a bit. I would get center in and offset out, then you have options. You can turn it around, the direction doesn't matter at all. An offset would have allowed me to either move it up and add ground clearance or rotate it a bit and get the pipe away from my tire. I have ordered a 12" case 3" in and out for my LS2. I wish an offset was availbabe, but it is not. Good luck! Quote Link to comment Share on other sites More sharing options...

RebekahsZ Posted April 28, 2012 Share Posted April 28, 2012 youtube "Dellorto Carburetors on 240z" for how the muffler sounds. Unfortunately just idling. Quote Link to comment Share on other sites More sharing options...

Josh280z Posted May 2, 2012 Share Posted May 2, 2012 I think the borla XR1 is not a viable option with me, because I want to stay with a 2" Quote Link to comment Share on other sites More sharing options...
joker81 Posted May 2, 2012 Author Share Posted May 2, 2012 KTM... Thanks for that! Love the sound...Any reason why it's an old set-up and not current? Why did you change it if you don't mind me asking? Thanks, Quote Link to comment Share on other sites More sharing options...

ktm Posted May 4, 2012 Share Posted May 4, 2012 Long story short - I did something stupid while installing a Slover ported head with an Isky cam. I sold the setup and dropped in an LS1. Quote Link to comment Share on other sites More sharing options...
