Well here is the exhaust that's going to replace the broken Catcos and American thunder flowmaster system. What kinda gain should i see, if any? This is my 1st Magnaflow system which consists of 2 - 2 1/2" Magnaflow cats and the 15620 catback. I've only had Flows on my cars so I wanted a change.
I will post up the mods made to fit the system, and a sound clip of both syestems. The catback was $388 at Summit and the cats were $94 each and since I went to Summit and bought them I get a $30 gift card. I also bought my Sportlines.


Right here you can see that I won't need to lengthen the I pipe, it goes to the front of the cats.


Here's a pic of the hangers that are on it.

Looks really nice.

I'll be down in a couple weeks to have you put all my stuff on . iwill get ahold of you when I'm ready. I have to have the cats welded in before I make the drive though. Well they might make the trip.

Looks really good. Let me know if you like it. I've been checking around for one for my "87 Z vert. Rick

Looks great.
I'm sure you'll dig the sound.

I didn't know you had the N10 dual-cats Steve.
No need to smog I thought, you just helping the ozone or what?

Brett is hookin' up the exhaust huh? What else do you do down there you magician?!

Yeah, he's kooking up the lca relocators, exhaust, and sfc's.
I just hate that nasty exhaust smell and I figured the cats aren't really going to rob power so why not. Plus they'll smooth out the tone a bit.
I heard a soundclip of an lb9 with this catback and it sounded awesome! I can't wait.

Awesome, that's the way to do it.
SFC's and LCA brackets made a diff on mine, you'll enjoy the solid feeling and better traction.
Hope to see/hear it soon!

I woulda had this.... if I didn't have weird ground FX.

I can't wait to hear it.

Me too! I should have it all done in a week or 2. I'm fixing the oil leak at the rear of the ntake and then I'm making the drive to Bretts shop for a days worth of anticipation.

Let me know when you come over. Brett's shop is literally a hop, skip, and jump from my place. In fact, my car will be less than a quarter mile from his place for the next week (long term parking at SFO).

I'll let you know. I'm going out to work on it today ,I can't wait till spring!

The Mangaflow is what I am wanting to go with. Can't wait to see how it mounts up and sounds.

looks great!! be sure to get an exhaust clip up when you get it on i wanna hear how good this thing is gonna sound

Let us know what modifications you had to do to install it.

I'm really curious to see how this sounds aswell.

Looks clean. As soon as you get everything installed let us know which one you like better. Flows have always sounded the best to me.

Yeah. let us know

It'll be a couple of weeks as I have a lot of other parts that I have to install but I will definatly post a clip of both exhausts so everybody can see the difference between the two.

so... got it installed yet?? I'm really curious to see how this sounds!

As am I.

AFAIK, he hasn't been to the Bay Area to get this done. Actually what happened instead is spelled out here:

Also, his Bay Area connection for installation (and mine) has been diverted by a noble cause.

We'll both be ready for the Future Famous "SO-CAL SMACK DOWN" in June.

i miss my magnaflow system on my iroc

Yeah, after installing the HSR I drove it for 2 days and the engine spun the #8 rod bearing. I returned the catback so I would have a little more money for a good engine build. Sucks cause I really wanted the Magnaflow. I'm alright with the Flowmaster and love the sound, just wanted something different.

id rather have a HSR than a magnaflow catback, and if you want something sounding different... do what i did


cut a 1 1/2" hold in the exhaust pipe before the flowmaster :P i have duals so i did it before each muffler at the rear and it sounds sweet, really loud but sweet
