I got my kit today and it was the catted y-pipe kit. I have mixed emotions about it. It is a very high quality kit and is all stainless steel. I do see a potential problem with the cats though. They do visual inspections of the cats and it might be a bit difficult to convince them this car does have cats. I also wasn't that crazy about the clamps so I'll be buying the wider clamps for it. Other than those two things , I feel this is a really nice setup and would purchase it again.Linky to what I bought:http://www.hawksthirdgenparts.com/in...?v=1&pid=25782 Here's a few pics:

Here's detailed pic of the Random Tech cats,.As you can see , this might be a little difficult to convince the emissions inspector that these are cats. They do have a steel matrix inside rather than a ceramic one and are supposed to be more durable.

And finally the clamps. I don't really like these and won't use them . I am happy with my purchase overall and Bruce has always treated me great. I have absolutely nothing bad to say about Hawk's whatsoever. This thread is just to show you what get. It's not cheap by any stretch of the imagination (1395.00 plus shipping) but I'll never have to replace any of it and it's right in line with comparable stainless steel headers for 4th gens. At this time , it is the ONLY longtube kit available for this swap . PERIOD.

i was just down at the exhaust place dreamin how good those would work on my car right now...

the guys there cant duplicate what they did at speartech so its gotta be ghetto'd up there some how...

if anyone thinks its cheaper to go with stock 01-02 exhaust.. guess again..i prolly have more into mine right now with all the ****in around then what the hawks bolt on system is worth

GMTech

They are kinda skinny. You'll be OK if they use a gas analyzer though. All they have to do it watch for C02 to go over 14% when the converters get hot and they will know.

I'll have to go through the sniffer but I should be ok . I didn't go with a huge cam and I've got HPTuners to tune it. I figure if worse comes to worse , I'll just throw some cat shells over 'em and run it through. It's not like I'm running an off road y or anything like that.

MrDude_1

let me guess...

you dont have a way to get the drivers side over to the passenger side where the I pipe is.... right?


same problem here... you can either do the kinda cruddy, but needed bend around like hawks does, or you have to get a custom crossmember made with exhaust cutouts...

i got this one off of someone on the board... works GREAT and it was pretty cheap...

GMTech

With a good running LS1, decent cam (nothing real big) and cats you'll probably have better tailpipe emissions then when the car was new...

yeah id like to run that but i went with the dumb *** torque arm...

that and now im questioning my spohn engine mounts as I had it up on the lift the engine is all over the front cross member.. not the 1/8th inch gap like it is on the speartech site.. id be lucky to get a peice of paper between the gap at the front..

GMTech

I had the same problem. I set the motor in and bolted everything up and once up in the air, I noticed the crossmember was touching the oil pan. Where the seam on the side of the crossmember was welded, there were several weld high spots. I had to unbolt the trans mount and jack it up so that I could get a cutoff wheel in there and take down the high spots.

If your motor isn't in yet, I smooth out all the high spots and maybe even "massage" that side of the crossmember in a little for extra clearance.

xtremeirocz

can you post a pic of where you are talking about. is it the back of the front crossmember at the fron of the oil pan sump?

GMTech

Can't take pics right now, its in the paint shop until next weekend. But yes, the front crossmember on the back side where the factory welded the seam across the back. I had several high spots that were making contact with the front of the oil pan sump. I was able to carefully get a cut-off wheel in there and take down the high spots

If I could go back and do it again, I would have taken a hammer and "massaged" that side of the crossmember to give me a little more breathing room with the oil pan.

I went with the Hawk's tubular K-member and rear crossmember.

so i wanna put in a ls2 in my 87 iroc but i hear there is no headers awailable for the swap, whats the deal here???

Knyghtmare

That really has me dreaming too... I would love to put some electric cutouts in with that too... I think I could spring for the longtubes themselves, but 700 for a y-pipe is nuts... I think I would just have a shop build a custom exhause after the longtubes themselves and be done with it...

badjuju342

Stainless isn't cheap and the cats were included in the kit .You figure in those 2 factors and the pricing is pretty much on the money.

so these headers will fit an LS2 right, its the same heads asnt it...i hope so, cuz i got a LS2 commin soon, so i need ehaders...will these do the trick, money aint an issue.

Ace

iTrader: (2)

must be nice, care to share.. ls2 is the same intake and exhaust layout as an ls1/6 they didnt re-invent the wheel too much with the ls2.. just fixed some of the ls1 problems and punched it out a bit

badjuju342

They should be just the ticket. The demand for these is pretty high but it's worth the wait IMO.

cool cool, i was figuring that the heads would be the same, jus wanted to make sure, now to find a ls2 and a procharger of i go to.

I agree... I'm a quality engineer and let me tell you... these SW LT 3rd gen LS1 headers are NICE! I love mine, haven't fired it up yet, but can't wait to. H/C LS1 with open LT's should sound nice! Now I just have to figure out this wiring

fattdaddy

Post sound clips please

5.0Camaro

yes they do fit good, i've had mine on for a good couple of weeks, they fit real nice, the y-pipe was a little tougher. If you have a drive shaft look from spohn then you'll have to cut it off, i also had to cut a little off the spohn crosse member to get them to tuck well. Other then that it fit fine, been driving with them for some time now, just finished driving the car from cali to MI averageing 29-32 mpg. Car sounded crazy with the open headers, and just sounds mean now with my GMMG exhaust. Hope everything goes well for you cause i LOVE my car right now. The ls1 pulls so hard compared to my old 305TPI, and even compared to my dads LT1 WS6.

I got mine a few days ago, and installed them that day. With the valve covers off they slid in very easily. Just needed to take off the steering shaft, and make a dent in one of the tubes to clear the shaft. Fired it up and it sounded good, but still loud as hell. I cant wait to get the rest of the system hooked up so I can really be able to drive it around. Although I am now concidering going with some cutouts after going to the track tonight and hearing all those open header big blocks.

5.0Camaro

haha, yea cutouts are always very cool. I love my GMMG exhaust just sounds killer when you step on it. Its always a good sign when you drive around and everyone gives you dirty looks.

Justin

92CamaroLS1

Lol...Is your GMMG the same as the ls1 GMMG cat back? If so I bet it sounds awsome, I love the sound of GMMG. I cant wait to get my y-pipe made so i can hear it like it should sound. I dont even drive my car around, it stays in the garage and I get dirty looks . Do you have any clips of your car around?

5.0Camaro

no sorry i dont have any clips as of right now, but i could get some. The GMMG was from my dads LT1, he got tired of it being so loud so said i could have it(made me happy), now he as a hooker which also sounds good(but nothing like the GMMG).

Justin

92CamaroLS1

yea if ya get any clips let me know, Im interested to see how it sounds.
