Got my Flowmaster American Thunder catback today! bought it from buyflowmaster.com and they're pretty good i reccomend them.

Me, my dad and yellow99 put it on in about 2 hours. Only hard part was the hangers but a little WD40 took care of that.

It sounds soo much better than my SLP's. i kinda liked my slp's though but they were just too loud lol. I'll make a sound clip sometime or another.

Nest on the list is Sportlines and cc plates!

 

Sweet....One step away from a full exhaust.

 

what muffler does your new cat back use? cant wait to hear it. what you gonna do with your old slp set up?

 

Does too loud really exist?

+1 on those hangers.....i've re-aligned the right side of my MAC cat-backs three times now to get rid of a vibration caused by the hassle of those hangers. Takes a huge amount of strength to get those on right. I used a large socket + ratchet to push towards the outside of the car while pushing with my other arm in the opposite direction.

 

dude i cant wait for some headers! super 40's, or thats what the description on the website says. Either sell it or trash it cause one of em is beat all to hell lol and its welded on the stock exhaust so its not very pretty.

 

cut it off with about 2'' of the stock exhaust attached and sell em for cheap.. i'll buy em.

I wanna hear em with your o/r H. i have super 40's welded in to a o/r X.

 

Sounds good to me lol they dont leak or anything. and flow fine just one has a few dents, i get some pics.

which do you want to hear? I have clips of the SLP's with my H if thats what you mean

 

i was wanting to hear the new cat back. bc it sounds like we have the same mufflers but diffrent mid pipes. wanna compare. PM with pics and price desired when you get a chance.

 

how do the tips look?

i didnt like the dinky little things on my 5.0.

 

they're pretty much stock ones with flowmaster engraved in them. i really wanted some SLP tips but meh..i'll survive.
