untill now i've had the "popular" cam/lt's ory+lm1 set up,

and most of you know how loud that set up is, i installed a LMII muffler, and it is a little bit more quiet, but still way to loud.

the next direct step would be the powerflow kit, but before i spent 300$ on it, and another 300 transporting them over here, are they worth it?

all opinions well acepted!

thanks!, ivar

I'm currently LT's, ORY, and LM1; have been for two weeks, and it's unbearable @ 2200-2600.

For around a hundred bucks it's a he'll of a lot cheaper.

doesnt that muffler replace the lmII muffler? i was thinking about adding more mufflers

i also found thunderbolt catalysts for around 100bucks, that could probably do it
fear the clearence though

For that price i'd look out for a factory SLP Dual Dual.

I have slp powerflo exhaust on my 99 TA and it has a good tone, thats not overly loud. I pulled the powerflo mufflers off and the car was loud with a ton of rasp. I'd definitely say they do their job.

I just welded in some cheapo cats and it tamed it down ALOT.

OP I recently changed to a LM2 as well. I still find it to be pretty loud also. I was considering just adding a couple high flow cats right behind the headers. That would be a little cheaper than the slp set up.

On the other hand I have wanted the new slp set up since it came out...

In my opinion no. The metallic thunderbolt cats are very compact. I would just make your own powerflo with 2 5 inch round Magnaflow bullets or 5 inch Borla XR1s

I would get the cats, my catted LM2 setup sounded better than my ORY/Dynomax anyday.

You can run a pair of Magnaflow #12866 (5" dia, 14" L-case $175 pr.), or a pair of #10416 (4" dia. 14" L-case $126) which would be a little louder.

how does those thunderbolt catalyst flow? they are at 59$ each, and i would finally be able to get the thing trouble free through inspection
