im lookin to make my car a lot louder. i rele like the slp loudmouth 2 catback. but im curious as to wat makes the most sound, is it the mufflers? or the catback. and if i bought the slp2 does it come with the pipes i need and everything?

thanks

get a aftermarket catless midpipe, and a aftermarket catback like the lm2 you want. the slp lm2 is a entire catback, not just the muffler.

midpipe and catback both will change your sound quite a bit.

wen u say midpipe are u referring to the x or h pipe

yea he is, I had the lmII catback with the slp catted xpipe and swapped the mufflers to lmI's. I would recommend a slp catted x with the lm's as they have sounded the best to me.

Keep in mind if you remove your cats by installing an off-road mid-pipe, your car will not pass inspection anywhere in the US. Some states/counties don't do emissions testing, but it's still federal law that any car that comes equipped with cats have them.

Also keep in mind that without cats your car is going to have a strong smell and it'll stick to your clothes and burn your nose at stop lights or anywhere you idle.

It'll sound great, but there are some disadvantages. IMO, catted aftermarket mid-pipes sound just as good and have no odor that is any stronger than when it was stock.

i only have flowmaster mufflers and its preety loud at but my friend only changed his mid pipe so far to an x pipe with cats and its loud also headers make it louder they all flow better than the sock so any exhaust change should make it louder

I have longtubes, o/r H and loudmouth II catback. After the tune I have no bad smell.
