I've had both 1's and 2's. Neither droned. The 1's are just a resonator, no packing or anything, and the 2's are similar to a glasspack in design. Both straight through. I have an MRT catted h btw.

 

What does your SLP 1.5 mean? What did you do to them?

 

he cut them open, took out most of the packing inside and weled them back together

 

That takes away a LOTof the drone and loudness right there.

 

Very true.
OP, what are you running for a midpipe? No matter what, the LM2's will not drone more than flowmasters if everything else stays the same.

 

exacty...i was going to say you might want to upgrade your mid-pipe first (if you havent already)

you will get some BIG sound gains from changing out the stock mid-pipe.

 

i have the stock h pipe and stock headersand just the flows.. ive been looking at ano/r x or h pipe but emissions testing and my dad wont allow it. also a catted one is alot of money. and i saw the resonators for only 140 bucks and figured if they were alot louder id pick em up. but i dont want alot of drone. i can get my hands on high flow cats for VERY cheap if that makes a difference in anything.

 

With the stock h pipe in it I'd go with the lm1's. The converters will keep the loudness and the drone to a minimum.

 

The SLP catback will bolt right up.

Very little drone.

I have MAC longtubes, CAM o/r H and SLP LMII catback. When I pass a car at WOT with my windows down it hurts my ears. My buddy was able to hear me coming from over 2 miles away cause I was WOT and he lives out in the country. They are loud!! But sound great.

 

im looking to just change out the mufflers not the whole catback. so will this just bolt in and i cant find anywhere that says"loumouth I" except for catback. are these LM 1?
