im about to install some lpp headers on my 2000 ss the car has about 60,000 miles do you think i can get away without replacing the motor mounts or would it be wise to change them out?



thanks, Brett

 

Of course you can get away with it. Majority don't change them. It's a preference and convenience mod since you're going to be in the vicinity. Same for plugs and wires.

 

If you have the headers out you might as well do it. I didn't when I did mine and had to take my headers out again to do the mm later

 

thanks for the info might as well change them

 

heads up.........be lazy...and expect to have pipes moving around and hitting the floorboard

 

Mine don't

 

i didnt do mine and no pipes hit anything lol,it is wise to change them when you do headers there not that much and its so much easier doing them at the same time, just do it, down the road you will thank yourself

 

You dont have to do it,, If your current mounts are in good shape, your fine, Most people do it, because it is so much easier with the headers out, and if you do have issues, youll wish you swapped them when you had the headers out.. its all your call though. If you do it, I would go with the polys, stay away from the solid mounts, they are more trouble than they are worth, You will hear opinions from all on this, but I have had all three OEM, SOLID, and Polys,,, Poly is the only way I will ever go.

 

I didn't do mine with my LT install. Started it up today with open headers, and had no banging.

 

Replacing your Motor Mounts should be Standard Procedure when installing LTs. They're relatively inexpensive. Anywhere from $50-70 for Polyurethane, which is the route I've always gone. If you upgrade to Solid Mounts they're a bit more of an invenstment at around $160. Yes, they can be a bitch to get installed, but they are the best insurance against, and only solution to, a Banging Y-pipe, which makes them well worth the Time, Money & Effort it takes to get them installed.

If you choose not to upgrade, you're rolling the dice. Some people get lucky and have no trouble with their Factory Rubber Mounts, others have their brand new pipes banging on their floorpan. If you happen to be one of the unlucky ones, just know that its nearly impossible to get to the Motor Mounts with Manifolds/Headers in the way, so expect to remove everything you just installed in order to fix the problem.

 

My solids from motovative were like 90 bucks

 

get poly ones. or get a umi kmember with the poly mounts on it lol thats the easiest. remember bp plasting fluid all of the bolts good every day.

 

where u find sum lpp headers at

 

bought them off some guy on craigslist near me

 

im waiting on them to get some more in stock. i already have there y-pipe

 

Yea I'm hopin that they'll go in pretty easy he put them on his car for like 10 minutes and decided he was gonna go turbo they look new. I'm gonna do it at my buddy's shop on a lift so hopefully nothing goes wrong and turns it into real long job.

 

I would do it, I didn't have the horror stories that everyone else has about lining the engine up with the hole to get the bolt through, I centered mine up just by lowering and raising the engine, but I just could have gotten lucky.

 

Solid motor mounts will give your car a solid feel, I would swap them out

 

I might as well wheres the best place to get a good deal on some poly ones?
