On the I5 Billy Boat made the first run of the performance exhaust, not sure on the second but I am pretty sure it was not BB. The touring exhaust was made by Borla, havn't a clue on the Alpha. I havn't seen any real photos of it so its hard to say.

Well I just got one for 295 shipped. Hopefully it's good to go at that price for a cat back figure can't really beat it.

Will do. I have been really bad about pics with the hummers. I'll see what I can get, movers come Wednesday to Friday then I'll be down a while but back up when we get the new pad in the great state of Oklahoma together.

I had thought about flowmaster but I'm not really a flowmaster fan any more after my borlas the flowmasters constant noise is honestly annoying. I liked the borlas and corsa because they are quiet under normal driving but when you step on it they come to life and sound amazing. I don't know about this cat back it may suck but for under 300 shipped I figured I'd give it a go if it sucks I'll do a custom borla. The stainless steel 50 series flowmaster is going to be at least 200 out the door with install.

I had a Flowmaster and got rid of it because the drone was very annoying. Now I have a Magnaflow and it's just right. Nice rumble without the annoying drone.

SWANK, do you have a 3 or a 3T?

Also, where in OK are you moving? I used to live in Tulsa. Really liked that place -- hope you do too!

Do you recall the diameter of the Flowmaster you had? And what series it was?

I have been thinking about a Flowmaster myself for a long time. Just haven't pulled the trigger because of other mods. :)

Not off the top of my head. I'll measure it later since it's exactly the same diameter as the Magnaflow.

Yeah, I know the drone bothers some people. My I5 with the Gibson has a rather loud drone on the highway but I kinda like it. It lets me know how my engine is running. It is also a lot of fun with the manual transmission when I bog the engine at low RPMs and set off car alarms. :giggle:

Hans I have one of each. Im moving to Norman it was there or Damneck, VA with Norman Ill always be home but boring work, Damneck work would rock but always out of town. I have a hot wife and want to keep her so Norman won out. I lived there before and love it way better than cali and yes Im from California (Palm Springs area) and there is some great stuff here but too much bs.

Starting to look around for an exhaust system. From what i have read the GM exhausts for the alpha are not compatible if you have UCP installed. Is this true. Alpha owners with UCP what cat backs are compatible? Thanks.

H3 ing I did see a little about that but I don't see how the UCP would have anything to do with this. Only issue with the gm performance exhaust is the tips you lose a lot of clearance at the rear bumper. So I guess while I'm here I'll talk a little more about it, it's not loud at all but it sounds good. Install was very easy, two cuts put the new pipe in place on the stock fittings and tighten three clamps. I did an airdoc at the same time with a k&n truck runs way better. For$700.00 total (flashpaq programmer, airdoc w/k&n, and catback) I think it was totally worth it truck is much smoother, and faster. MPG gain was about 6.5 BUT! That's also going from my wife's around town driving to me on the freeway too. We should be getting into the new house today so this week we should start to see the new around town mileage.

I did the flowmaster 40 custom exhaust and I love the sound but I am from MS so I.m use to it. There are 2 notches in the back bumper where mine come out, also the exhaust dude ran my pipes high then angled them down through the notches.

I like the pipes routed like that. I had some custom ends on mine in the same fashion.




Well, at least until I hit a few rocks. I still managed to clobber the tips somehow . . .

Nj3t her around town average was 11 I got 17.5 on the 150 mile trip after the install so it's a combo of the mods + freeway vs in town driving I'm in the middle of a move so not sure what my new around town mpg will be. If freeway holds at 17.5 I'll be stoked.

Yaa I don't know how the UCP would have come into play with a cat back product but just wanted to ask. Can you post some pics from underneath and of the tips. Are the tips removable? I really don't want them hanging out or down but I guess I can have a local muffler shop mod that if needed. Thanks for your info.
