white4d96 Posted April 1, 2011 Author Report Posted April 1, 2011 dune buggy project. With the smallport motor? Nonono. This thing's a fucking ticking time bomb, hence me wanting to chuck it ASAP. Although I still kinda wanna do a crazy LQ1 Locost or something of the like Quote
Jonpro03 Posted April 1, 2011 Report Posted April 1, 2011 1G =/= 2G mani I don't know anything about the CTS. Quote
white4d96 Posted April 1, 2011 Author Report Posted April 1, 2011 But can I use the 2G mani's, is my question. Quote
Jonpro03 Posted April 1, 2011 Report Posted April 1, 2011 they won't have the right downpipe location. Quote
white4d96 Posted April 1, 2011 Author Report Posted April 1, 2011 (edited) Crap. So I guess I'll be porting my manifolds. Wait, large port manifolds were 2G only correct? Or am I missing something here? Edited April 1, 2011 by white4d96 Quote
tornado_735 Posted April 2, 2011 Report Posted April 2, 2011 this thread is turning interesting. Quote
white4d96 Posted April 4, 2011 Author Report Posted April 4, 2011 I hope that's a good thing and not a WTF STOOPID NOOB thing I just wanna have all my bases covered before I start ripping shit apart. Jon, Bob, what did/were you guys going to use for exhaust manifolds? If I was going to build a DP could I use other manifolds? Push comes to shove I guess I'll try making a front log but idk if I'll be any good at that... Quote
Crazy K Posted April 4, 2011 Report Posted April 4, 2011 I recommend the 1997+ rear exhaust manifold, as it flows better than the log. and that is what i would do... Quote
RobertISaar Posted April 4, 2011 Report Posted April 4, 2011 if you're going to go with a custom downpipe, you can use pretty much any 60V6 exhaust manifold from gen2 upwards... the stock 3500 front "semi-header" is nice, though it MAY get uncomfortably close to your fan brackets and require modding of the dogbone mounts.

BXX Posted April 5, 2011 Report Posted April 5, 2011 Yeah, the Malibu and G6 route the front exhaust down below the engine, wont work in our cars. Quote
Jonpro03 Posted April 5, 2011 Report Posted April 5, 2011 It'll bolt up to the engine, but not your downpipe. Quote
white4d96 Posted April 5, 2011 Author Report Posted April 5, 2011 Okay. How far off is a 2G downpipe going to be? Is it 'cut a foot or so off' off or 'WTF!?!?!' off? Quote
RobertISaar Posted April 5, 2011 Report Posted April 5, 2011 worthwhile question: is the 2nd gen downpipe as bad as the 1st/1.5 gen pipe? as in, there's a huge as restrictor and it's double walled? Quote
BXX Posted April 5, 2011 Report Posted April 5, 2011 Just get a custom 2.5" DP made. Should run around $100 to $200 at a decent exhaust shop. Quote
Jonpro03 Posted April 5, 2011 Report Posted April 5, 2011 That's too much money, run no downpipe! Quote
RobertISaar Posted April 5, 2011 Report Posted April 5, 2011 That's too much money, run no downpipe! i, for one, am not fond of carbon monoxide poisoning.... though i guess it would allow you to tune fuel requirements by smell... Quote
Crazy K Posted April 5, 2011 Report Posted April 5, 2011 any 97+ gen 1 or gen 1.5 w-body will have the correct downpipe to meet the newer 97+ rear manifold... I have a clean enough used 97+ downpipe, I was just going to cut and clamp myself.... i doubt any other vehicle will have a factory downpipe that has the clearance to fit in our cars... Quote
white4d96 Posted April 5, 2011 Author Report Posted April 5, 2011 Just get a custom 2.5" DP made. Should run around $100 to $200 at a decent exhaust shop. Around here, try $300+. I'll just have to try my hand at making my own. Quote
RobertISaar Posted April 5, 2011 Report Posted April 5, 2011 where's the pic of Adam's downpipe when you need it? to be fair though, my welding work doesn't look much better if any. Quote
Jonpro03 Posted April 5, 2011 Report Posted April 5, 2011 FWIW, I just had my downpipe fabricated for $60 at a muffler shop. Quote
19Cutlass94 Posted April 6, 2011 Report Posted April 6, 2011 If anyone would like to contribute to my header fund, Ill sell my custom downpipe shortly after! Quote
19Cutlass94 Posted April 7, 2011 Report Posted April 7, 2011 Yep.. 2.5" from the flange on with o2 bung Quote
