Who uses them?

Are they worth it?

Any side effects?

Thanks.

 

smooth bellows is just a waste of money don't bother wasting $50 many ppl from this board will tell u

 

Go to home depot and make your own for $5....I was pissed when mine came in the mail and I realized how cheap it would've been to fabricate myself.

 

Mostly an appearance mod,The SLP bellows looks much cleaner than the HD mod.You can get the SLP one cheap on ebay.

 

Here is an inexpensive alternative:

You would want the 4to3.5"

steve ur tha man! i was bout to get an SLP bellow soon but u might have just saved me $35.00

the stock accordian bellow isnt the best flow but i dont know if a new smooth bellow is really good for the 5-7hp they claim.. prolly like 1-2 MAYBE on a dyno. the only reason i might still want to go with the SLP is because i have an SLP airlid and the angle on their plastic bellow is a perfect fit. this might not be the case with the product u linked above.

anyone with an SLP airlid tested any bellows and have some opinions?

SLP did change there design so it looks less like the Fernco.

The new one looks alot more professional too.

 

I agree with steveC... I bought the Air Flow Systems bellows and I love it... get the 4"/3.5" one, all I did was trim about an inch off the MAF side, and I think it was one and half inches from the TB side of the bellows, and I cut a little notch on the top of the TB side (look at your TB and you will see where you cut the notch). I love it, it fits perfect.
