MSA Twice Pipes

[FreddyZ78]

I'm going to be buying the twice pipes kit from msa in a few weeks and was wondering if anyone knew what size the piping on the kit is because it didn't list it on the website. Thanks!

The pipes are 1.75", need to be modified to fit correctly, are made from common steel, exit the car horizontally so they don't match the stock cut out, drone at 2.5k rpm, and are loud enough to earn you an easy ticket in most states.

 

...but if you can deal with all of that, they sound pretty good and seem to be fairly popular around here...

I love my twice pipes, they look awesome and make the Z sound like a 60's ferrari, however you will need a muffler guy to fit them for you if you cant do it yourself, they will not mount right straight from the box.

Around how much would I expect to pay to get it installed? Also does the kit bolt onto the stock exhaust manifold?

[DatsunZman04]

I think they sell the kit to go to the stock manifold just adaps to 1" and 7/8 (stock)  But most people install a 6 to 1 header or 3 to 2 to help divide the twice pipes. Its your option.

I put mine on stock manifold but it still didnt line up right, the muffler guy charged me 75$ if i remember correctly.

They are loud, and the sound gets old if you drive at constant speed on the highway for extended periods. Out of the box, don't expect to bolt them on and go, as you will have to invest a fair amount of time and effort attempting to get them to fit and aligned, which they likely won't. If I were to do it again, I would have welded the system together from the header back with only one clamping point, as the exhaust clamps failed me a couple occasions at the worst possible times prompting a roadside fix (probably my fault). Go into the purchase with these things in mind.

 

With that, they get my full endorsement and 100% recommendation. One of my more memorable modifications.

Do they enhance the performance of an L Series motor?

[tooquick260]

I just took mine off. Going turbo! To bad you are not close could make you a deal.

 

Yes they are louder but worth it. What a N/A motor should sound like. There is a drone at certain rpms.

 

Performance possibly a little.

[morbias]

I read they actually decrease performance...

I have 3 complete sets, and one incomplete.

I have so many sets because I bought them cheap(mostly at MSA garage sales), and with multiple sets I can set them up any way I want.

 

After setting these things up I would recommend MSA's 2.5" setup. Noise level is the same, but you can easily and affordably use one system and add in extra sound/drone reducers. My Favorite way to deal with those is one of those Autozone Thrush Turbo mufflers on the rear(not the MSA one) part number 17715(or you can use their welded series with is a flowmaster), and the center muffler(antidrone premuffler) from a mid 90's toyota camry v6 to put in the trans tunnel. Quieter than stock at idle with a low growl(even with the L24), and comfortably loud at freeway speeds. No drone. Its not quiet at freeway speeds, but its not obnoxious at all.

 

Matter of fact I would trade one of my twice pipe kits for one complete 2.5" MSA kit and another $30 Thrush Turbo muffler... lol

They're louder than...well...they're loud.  Cruising rev's are loud.  Running it out is loud.  The sound is unique, though, as they sound like two slightly out of phase motors running at once.  It's a very subjective thing, but I don't really like the sound.  I'm looking at switching to a more conventional 3in single pipe setup.  The only reason I have them is because they came with the motor that I bought off of ZGad on here.
