i have a lowered car. lowering springs and no isolators. are mac midlength headers a good investment? are they as good as a longtubes powerwise?

i know a few people who run 'em (one guy is lowered 2" i believe) and he ran SLP LTs and had clearance issues with them. he switched to pacesetters and hasnt had any problems since then. so i dont see why you dont go with LTs but you have your reasons. as for power difference, i think ive heard its about 10whp, i could be wrong but thats what ive seen around here. might not notice but if you go big cam or stroker sometime, youll wish you had longtubes.

10 hp isnt that big of a deal to me. just confused. i know how LTs often recommend changing to poly mounts and didnt feel like swapping mounts. ya im not planning on a stroker or cam on this car. just going to keep it stock internals

do mac midlengths require poly mounts like LT's?

it depends on how far you want to take the car .....yes you'll wish you had them down the road ... how low are you lowered ?

nemss1

i have hotchkis 1.5" drop springs and the rear isolators are removed. im just doing all bolt-ons and weight reduction on the car

yeahhhhhh i have mac mids i like them and all... but with a head/cam car i will be needing some longtubes.... even more money spent

Just go with hooker or pacesetter long tubes.

You'll wish you did later on, if you go with the mid lengths.

just do it right from the start ....i said the same thing ....i want a cam car and some weight done now im in the 10's and want 9's and i weigh 2950

nemss1

do i have to change to poly mounts with LT's?

nemss1

ya i have a buddy that was the same way. he kept wanting faster and faster. now he has a ten sec car. i might catch the bug someday too

iTrader: (5)

trust me you probably will

nemss1

i heard LTs need poly mounts. could i keep the stock mounts? heard they are a PITA to change

iTrader: (5)

im not sure ....i had speed inc put them on ...

Zzzzz

Poly's don't add much cost to the job (figuring on you doing the labor yourself). Given that, it's hard to find a reason not to do it when the manifolds are out of the way.

nemss1

id like to install the headers myself to save on labor cost

just worried bout having to change motor mounts

nemss1

are they hard to do yourself?

ndfrsd6

iTrader: (5)

that you dont have to do i still have my stock motor mounts...

nemss1

do u have any issues with the y-pipe banging the floorboard? did u have to make any adjustments?

ndfrsd6

iTrader: (5)

i have true duals so no y pipe so i cant answer that for sure ....

nemss1

what is your opinion on hooker LTs?
