    Anyone have any good suggestions for an exhaust to get? I was looking at a random downpipe and high flow cat but idk what headers or cat back to get. Also keep in mind I will be top swapping eventually so I dont want to spend another grand on exhaust when I switch everything.

    random tech downpipe is junk.

    you dont need a high flow cat.

    any chambered muffler is going to drone and sound like crap.

    Buy catless speed daddy headers. Keep the stock catback. Done.

    if you are topswapping its not even a question get headers, it makes the car sound good with the stock catback and will let you flow with no problems

    Yea I will definately be top swapping in the future I have already gotten prices for most of the parts and talked with morad about them. Right now everything is stock and I have the SE catback so should I still leave that or swap the valance panel for like 50 bucks and get a dual and if so which one?

    Who knows...its your car do what you want. If you swap catbacks you can also get a GXP V8 catback...they sound a little better from what I hear.

    it wont matter whether you want single or dual outlet exhaust performance wise, just whatever you thinks looks better...its before the catback is what you wanna change

    Ok so I started looking around for those Speed Daddy Headers and there are some people seriously flaming about them and I cant find them anywhere so moving on I need a new option.

    I need
    Headers and Downpipe

    Ill get the cat back at a later point if I feel like switching to dual outlet.

    Who is flaming Speed Daddy? Everyone here that has bought them never had an issue. Don't know where you got that...why would we recommend something we knew was bad?

    He's talking about the old speeddaddy's that were just pacesetters. The ones currently being sold are good. You just didn't do enough research [there have been two generations of speedaddy's].

    im N/A GT and im running wbodystore.com PEM headers, ZZP ceramic crossover pipe, zzp catless 2.5 DP, and a SLP catback that i got for $100. it sounds great and performs great i have a real deep pitched exhaust to mainly because i put the shortened dog bones with polyurethane mounts it give the exhaust a really deep pitch.

    shorter dogbones are used to put the axels back in line after lowering your car and would have no effect on the pitch of the exhaust, but glad you like your exhaust!

    LOLz. Shorter DB's and Poly mounts do nothing for sound like said. I honestly can't believe you also bought PEM's from WBody Store when you could have taken a dremel and hogged them out for free and sanded down your crossover yourself and painted it with 2000* engine paint.
