Hey guys I was just curious which one of these axle-backs would you guys recommend? Also is there any power increase with a Muffler Delete system?

 

I've never heard the pypes bomb but the slp LM tips look great! I run them with my pypes mid muffler system!

 

I loved my slp lm2s!! Havent had the boomtubes to compare the two though

 

Power increase is reported to be negligible if at all. Sound is great though with my SLP LM's, and there was a nice weight savings of around 16 lbs. I've been happy with my LM's, which were one of the first things I did to my Mustang.

 

I bought a set of Pype Bombs a month ago. Great quality and fit. Looked awesome & super loud. No effect on my trap speeds at the dragstrip, so I'd say zero power increase. I took them off after less than a week as they were too loud. Supercharger = 50% more airflow and 50% more volume, so it was too much. On a NA car, they'd be nice.

 

Yea I plan on staying N/A. I actually prefer the sound of the Pypes Muffler Deletes to the Bombs but I'm just not sure what I should do.

 

Exhausts like the SLP LM's and other muffler deletes sound great IMO, and are borderline, but not too loud for most stuations if that is the only modification to the exhaust. It seems like a lot of people sell theirs though, when further exhaust mods are done, like long-tube headers, off-road pipes, and/or free flowing cats, as those will make the muffler deletes significantly louder, and sometimes change the exhaust note to something more unpleasant.

 

That's why I pulled mine off. I have high flow cats & X-pipe, and a supercharger, so the Pype Bombs are too loud. Plus, they sound a bit raspy (mostly due to the X-pipe, but amplified by the muffler deletes).

 

I'm running Pypes LTs, high flow cats, x-pipe, bombs. here is a link to a couple of clips. They are prior to adding the cats. I was insanely loud without them.
