My LTs, o/r X, and weld in flowmasters were simply TOO loud at crusing for me. Like I said, loud loud exhaust gets annoying when your just driving around and acutally using the car (vs racing etc)

I still watch your dyno video all the time....I LOVE the sound of your car! I wish I could run LTs and an O/R X here in Cali!

From listening to exhaust clips, I like the LMII better...just sounds a little deeper, and not like loud as _______ like "RAAAAAAAHHHHH!!!!"

this is one mod im glad it will take a little time to save the $$ for since the decision is going to be tough.

Just buy a seperate o/r X and swap em out, there only around 180 bucks.

Not so sure what the cops could/would do to ya though.

Its a big fine here in Cali if caught without cats. Something like 600-1000 per missing cat. lol

I was going to go SLP but I just couldn't decide. Basically from what I gather it's all about preference. Both are great exhausts... the LMI is louder, more raw, while the LMII is quieter, but deeper and more tame. As far as quality I'm sure they are identical and what it comes down to is just preference in sound. For me, I found a killer deal on Magnapacks so I didn't go SLP after all. Magnaflow seems to have a good track record, and people on the forums seem to love the Magnapacks on the 4.6.
