just bought some that size last night it was late and i was tired, im not FI and wont be for a least year, will it hurt performance? how bad? should i call and cancel order and get 1 5/8?

bump.........anyone out there?

yea u will probably loose some power if you install those but you could always just keep them in the garage. there is not enough back pressure in the headers if you arent F/I

ok its 0104 here in afghanistan and i must go to sleep, i have a long day of trying not to get killed by the taliban tomorrow so i will check this tomorrow night here. thanks for any input the may show up. i looked for MAC 1 5/8 could not find any dont think MAC makes them, thier site does not list that size and LMrestoration.com is a typo i think because the part # is the same as the 1.75. goodnight

noticable power loss? since im going from stock headers and midpipe to LT's and prochamber, mabye 10 HP gain instead of 20?

You can buy the MAC LT's with 1 5/8 inch primaries here.

In case you're wondering what the MAC LT's with prochamber looks like together, here's a pic of a forum member's set when they were delivered.

yes but i still think that listing on latemodelrestoration.com is a typo. its the same part number as the 1.75's listed on the offical MAC website

I think he may be right since I have looked for that size in these headers and not come across them. I am not sure how much the mid lenths would hurt since they are not full LT so the 13/4 might not be as bad , just a guess.

They are 1.75” primaries. Sorry for the confusion & thanks for pointing out our typo! Have a great weekend.



Thanks,
