    Re: Thinking of doing a custom exhaust on my V.

    this is not helping my wild hair to do a muffler delete.

    did one on my 95 GT... loved it. didn't keep my mufflers, though. Won't make that mistake again. in fact I'm going to mark my mufflers to make sure they don't switch them for junkers during the delete.

    my neighbors are NOT going to be happy with me when I leave in the mornings around 5:30

    Re: Thinking of doing a custom exhaust on my V.

    Search "CTS-V muffler delete" on youtube and you'll find a few clips of exhaut sounds. I think I like the sound of stock cats and resonator with no mufflers. Its still emissions legal that way if thats important to you, but sounds like theres not too many issues with resonance etc. I think I'm going to go that route, then if I dont like it I'll add magnaflow mufflers and x-pipe (in place of the resonator) for the "poor mans magnaflow". Even if I do the poor mans magnaflow with labor I'll be in it for $200-300 less than any of the aftermarket systems.

    Stock everything no mufflers sounds great, there are two rpm zones with some drone but not too bad. I get a lot of looks and compliments, some guy walking his dog yesterday came wandering into the street to give me a big thumbs up as I drove by.

    $100 labor plus the tips which were maybe $30 each, lot of options on the tips.

    I'm being quoted 125-150 to remove the mufflers and reuse my stock tips... I remember having it done for 50 on my 5.0 back in 2001...

    "what kind of car you got?" "it's just a GM with an LS2"... that question irks me. Next time I'm saying Lamborghini...

    Re: Thinking of doing a custom exhaust on my V.

    Guys, remember that the stock resonator IS an x-pipe. There are pics floating around somewhere here of one cut open. It just has packing to make it quieter. I have muffler delete with stock everything else and it sounds awesome. The stock system is actually very good 2.5" mandrel bent stainless. GM should have used a more agressive muffler and not used those whimpy tips. Please please please do not re-use those tips. Summit has nice low priced tips. Heck even walmart and pep boys have half way decent tips.

    Don't call and ask shops for prices. Just pull in, get your car in their bay, and tell em you want to chop the mufflers off. THEN ask what the cash price will be. I paid $50 for them to cut the mufflers off and put stainless pipe and my tips in their place.
    Also, I have a topic somewhere here about tips. I got a set of 4" round, slant cut, rolled lip, stainless tips made by cherry bomb. They were only $25 apiece and look great.

    The problem with aftermarket tips is they make it look like your car is hopped up, and makes people want to race you even more. I don't know what it is about the V, but guys in any kind of performance car would not leave me alone. The one part of the V I don't miss.

    I guess I'm not following you on where the problem is?

    I'd be interested in the Corsa if you still have it.

    Re: Thinking of doing a custom exhaust on my V.

    Muffler delete is the way to go. I've learned to push the RPMs through the 1800 to 2000 range to reduce the drone that my kids hate. I still have stock tips, but I'm looking at some new tips either tomorrow or early next week. I asked the local Midas shop for an estimate and they said $200, I called back 2 days later and said "if I bring $100 cash will you do it?" and the guy didn't even hesitate, but they had shitty tips in stock. Cash is king...

    IMO I think the straight pipes on the 1G CTS-V sound much better than any Corvette of the same age or newer.

    I did change my NAV unit to display the instant MPG though, I need a constant reminder that my love of this car and the sound has an adverse affect on my wallet.

    Agreed, you really shoulnd't have to pay more than around $100 for this and the 1800-2K drone is easy to deal with. I just flipped to the avg mpg and saw 11.9... flipped it back to temp pretty quick. I'm switching from 4" straight tips to 3.5" slanted that are sitting in my garage as soon as I bother to take it to a shop. Should have gone slanted in the first place.

    Re: Thinking of doing a custom exhaust on my V.

    i've been reading into this thread and was wondering about the dual in/dual out flowmaster with muffler delete? has anyone done this yet?

    Also, I can shead some light on some exhaust set-ups. I can say i've heard a corsa catback on a ls2 gto, and it sounded AMAZING! it SCREAMED, and had a very awesome, unique tone! However, i am not sure if it was accompanied by headers or not. And as the owner of the corsa said, it was too quiet, perhaps it would be best to try and delete the restrictive cats and resonator? The hooker aerochamber is a great muffler. It sounded awesome in my bmw 535i (inline 6), and on my camaro ss. It was a little more quiet than i'd like on the camaro, but didn't have that nasty flowmaster tone. I am aware that the exhaust set-up is much different on our cars than camaros, but you can get a general tone idea due to the similar LS engines. looks like i'll most likely be trying oem muffler delete first!
