AWeb80 Posted July 4, 2008 Report Share Posted July 4, 2008 Got the pipe from here http://www.speedwaymotors.com/p/5423,417_Side-Pipe-and-Exhaust-Hook-Up-Kit.html?itemNo=side%20exhaust I live 10 mins from the warehouse ...... Stock 3100 DP.......BARELY 1.5" inside Diam.........that is horrible.... Stock Flange ready to weld......... Not much room there.....~1" either side...so my measurements had to be RIGHT Now the ugliest welds in the world...........But I don't care, nobody will see them, they work, and I have the satisfaction of doing it myself.... Didn't take any measurements.....ran out of time...was too busy fitting and such to worry about that.... Here it is drying w/ the VHT High Temp Coating..... Here it is installed.............................PERFECT FIT............that made my day great........ This is one of my fav mods......it opened up the mid and HIGH range like no other........4-6K RPM is just crazy......and 1/2 throttle off the line is effortless..... I will eventually do 2.5" back to the Y and then 2.25 from the Y back w/ mufflers and a rez up in the 2.5" I thought it would be pointless to do the larger exhaust w/ a DP that is 1.5" in Diam.....so this will open it up a lot when I get the full exhaust on. Here is the vid of my doing some WOT's and Down shifts..........it is soooooooooooo loud now....I LOVE IT Quote Link to comment Share on other sites More sharing options...
BXX Posted July 4, 2008 Report Share Posted July 4, 2008 Wow, your down pipe does look soooo different from mine... What the hell was GM thinking?? BTW, ugly ass welds, but nice that you finally got it done and on.. Quote Link to comment Share on other sites More sharing options...
bodeen2007 Posted July 4, 2008 Report Share Posted July 4, 2008 those welds ain't bad and if they don't leak then their doing their job so be proud that you didn't have to pay somebody else to do it. Awesome job. The car sounds mean as hell.... I need to do this to my car to make mine even louder. Quote Link to comment Share on other sites More sharing options...
BXX Posted July 4, 2008 Report Share Posted July 4, 2008 Yeah, I just now watched the vid.. His almost sounds as loud as mine. Sounds pretty damn good.. I oughta take a updated vid of mine sometime.. Quote Link to comment Share on other sites More sharing options...
GOT2B GM Posted July 4, 2008 Report Share Posted July 4, 2008 Shoulda had your brother weld it Adam...... but nice fitting work. Quote Link to comment Share on other sites More sharing options...
meltboy1 Posted July 4, 2008 Report Share Posted July 4, 2008 my 89 is still louder.. custom rust and rot ftw! I gotta learn how to weld... lol I really like it though... just another reason for me to want your car... Quote Link to comment Share on other sites More sharing options...
Venom Posted July 4, 2008 Report Share Posted July 4, 2008 So any tips on removing the bolts at the flange? My donught gasket is leaking and I need to remove the bolts/springs to replace it, but I havnt taken to good of a look to see the best way to do it. Sounds awesome by the way.

wildbill Posted July 4, 2008 Report Share Posted July 4, 2008 Nice install. I agree with Bo, as long as they don't leak, they're good. Sounds mean! Quote Link to comment Share on other sites More sharing options...
89SupremeCutty Posted July 4, 2008 Report Share Posted July 4, 2008 wow! good job on the downpipe. i love how it really picks up from 4k-6k. sounds awsome too. Quote Link to comment Share on other sites More sharing options...

Long extension from underneath with a u-joint type socket and a impact if you have it.. Which I know you do.. I wanna step mine up, but I am gonna get a stock one from the JY first and take it to a shop to have them follow it as a template and of course, it will be done in stainless...

Artemis Posted July 4, 2008 Report Share Posted July 4, 2008 Would the LQ1 have a similarly small DP? Quote Link to comment Share on other sites More sharing options...
z34Phoenix Posted July 4, 2008 Report Share Posted July 4, 2008 i know my 96 dohc had a 2.5" dp stock. the pipe did have some press bends that prob took it down to 2.25 but it isnt bad at all... and being stainless you know it will last vs making a new one out of mild steel Quote Link to comment Share on other sites More sharing options...

MonteCarloDude Posted July 4, 2008 Report Share Posted July 4, 2008 That's great. I have been thinking about doing this to the monte, I think i may just have to now. Quote Link to comment Share on other sites More sharing options...
AWeb80 Posted July 4, 2008 Author Report Share Posted July 4, 2008 THis was deff better than spending $250 at a shop.....I love doing my own stuff. The car is a lot louder at idle now....I love it. I wanted to do stainless, but my dad doesn't have the right wire to weld w/..... I got better as the day went on... I had a tendency to blow holes through the pipe, so I had to layer it on thick just to make sure there were no leaks.....LOL ...and Bob, any pics of your stock DP?........how much different is it than mine? Do you think that maybe in 96, GM just started using the 3.4 DP's for the 3100's? Quote Link to comment Share on other sites More sharing options...
jeremy Posted July 4, 2008 Report Share Posted July 4, 2008 it looks bad, still seems slow but does sound good..... Quote Link to comment Share on other sites More sharing options...
EviLette Posted July 4, 2008 Report Share Posted July 4, 2008 it looks bad, still seems slow but does sound good..... 3100 = not fast. Though I'm sure he'd outrun most of the 3100s on the road at this point. Provided they dont have cams, heads, bore, etc. Quote Link to comment Share on other sites More sharing options...
AWeb80 Posted July 4, 2008 Author Report Share Posted July 4, 2008 o ya, I've stayed w/ a 3100 w/ 3400 heads/intakes..... it pulls pretty hard for a 3100....on a good down shift in to first, the front end gets squirrelly... Quote Link to comment Share on other sites More sharing options...
runt Posted July 5, 2008 Report Share Posted July 5, 2008 Ahhh yes! It might look like poo, but it seemed to make a difference. I'm curious what will happen if/when you open up the rest of the exhaust. Quote Link to comment Share on other sites More sharing options...
MonteCarloDude Posted July 5, 2008 Report Share Posted July 5, 2008 I'm curious what will happen if/when you open up the rest of the exhaust. My guess would be not much, The stock DP is junk on these cars, But the rest of the exhaust is ok. it looks bad, still seems slow but does sound good..... 3100 = not fast. You can say that again. Now a S/C 3100/3400 would be Quote Link to comment Share on other sites More sharing options...

I am pretty sure I could easily hang with him if not pull from him.. And Adam, I will try to get some pics next time my car is on the lift at work and I have a camera with me..

Addicted To Boost Posted July 5, 2008 Report Share Posted July 5, 2008 Sounds good, throw some magnaflows on it and make it a bit louder! Quote Link to comment Share on other sites More sharing options...
EviLette Posted July 5, 2008 Report Share Posted July 5, 2008 OMG.. Adam your car really does make me want to cry. It's just that awesome. If I didn't know for a -fact- that there was a 3100 under your hood, I would call you a liar right now... watching that accel, especially how quickly your tach is jumping ABOVE 4k... Just dead sexy. I know I said it before, but DAMN. Quote Link to comment Share on other sites More sharing options...
AWeb80 Posted July 5, 2008 Author Report Share Posted July 5, 2008 LOL Thanks guys! I had a guy walk up today who hasn't seen my GP in a while and he asked if I had a modded motor.....cause it sounded sweet. I LOL'd and said no....mostly stock. I love the new sound......amazing how it opened up the sound.....I went down a HUGE hill tonight and used 1st gear as an engine brake and the RPM's were hangin around 3500-4k and it was cackling and cracking all over....LOL sounded sweet Quote Link to comment Share on other sites More sharing options...
