I like it man. Sounds like a pretty lopey idle, I'll bet its pretty loud with some throttle. Haven't had any trouble with the law and my exhaust. At least not yet. Heres a video if you'd like a taste...

Loud sounds like sitting at a red light and droning out a back halfed big block car with dumps

 

Sounds good! Thats about what mine sounded like before the cam went in. I have pace LT headers and ORY, my tips are the bigger 3.5" slash tips which I think give it a deeper tone but louder yet. I loved the sound but it was just too loud for the street.

^^ I agree thats too loud!

 

I had true duals (cat-less) dumped preaxle with Hooker Super Comps with a MS3 on a 114and it is down right loud as **** (moving to ARH 1 7/8" though). I would say go with the borla bullit atleast. Remember the LM1 resonator is completely hollow so putting on just about any other bullit will tame it quite a bit. I have had a LM1 on both my TA's, love the sound but not crazy about them with a cam swap though.

 

This is what mine sounds with TSP V3 cam, 5.3L 2.5 heads, pacesetter lt's, ory and magnaflow catback. It's pretty quiet if you just cruise along at normal speeds, when you get on it though it sounds like a rocket.

Wow! That sounds great man! I may have to suggest the same cam and heads to a friend for his 98 Z28. He has LT's/ORY into Magnaflow Catback and it sounds good as is. That car of your's really winds. Hell yeah!

 

Thanks man, i'm pretty happy with the setup. I need a new stall but other than that it runs pretty good.

 

yeah, why not just go to an exhaust shop and have them throw in a 2nd bullet muffler/resonator on before/after the lm1 resonator. that shouldn't cost too much at all.

some people also say this lm2 resonator is quieter..

Get an LM2 resonator. If you still don't like it add the powerflow option. The powerflow is very mild but still sounds good when you want it. Drops the rasp too. Otherwise modding the exhaust isn't worth the trouble, like was said before just get a second catback.
