Aj11 Posted November 25, 2014 Report Share Posted November 25, 2014 i have a 2002 Pontiac grand prix gt. 3.8L v6 a few weeks ago it developed some issues. smelled like eggs, red lining at 2200rmp no power up hill and terrible mpg. i now know i need a cat, but here's my thing, all of my friends keep telling me to get a high flow cat. there anywhere from $50-$120 bucks. but the oem cat for my car Is $500-700 bucks. i don't know if it's me but that just doesn't add up! i don't really care about hp, or performance. i prolly won't have the car longer then a year. i just want to pass the inspection that's coming up in 3 months and make it up hills again! if i can get those things with a $50 part please let me know! but if it's the pipe dream i think it Is, please let me know! only.need 6 more months out of the car! jvc deck stinger 1800 front hc 2000 kinetic rear 2 runs of 1/0g big 3/4 ct 60.4 2 ct 1400.1 ct EXO 15 d1 lots of deadner type r comps front stage 6 kicker tweets rear stage lots of great stuff coming soon ho alt more bats ct comps for front stage more deadner sweet amp rack lots of L.E.D lights new deck (thinking 80 prs, or flip out) Link to comment Share on other sites More sharing options...

yurvalentine Posted November 25, 2014 Report Share Posted November 25, 2014 The high flow will pass visual, and they should normally pass a sniffer test. Just make sure you buy from a trusted retailer. Link to comment Share on other sites More sharing options...

Aj11 Posted November 25, 2014 Author Report Share Posted November 25, 2014 i have a guy who can hook me up with a inspection. but i don't want it to be so impassable that he can get in trouble either. this spring i should be making steps towards getting my 09 G8 but with my.current Job i do allot of driving. so i still need this car very much so. jvc deck stinger 1800 front hc 2000 kinetic rear 2 runs of 1/0g big 3/4 ct 60.4 2 ct 1400.1 ct EXO 15 d1 lots of deadner type r comps front stage 6 kicker tweets rear stage lots of great stuff coming soon ho alt more bats ct comps for front stage more deadner sweet amp rack lots of L.E.D lights new deck (thinking 80 prs, or flip out) Link to comment Share on other sites More sharing options...
yurvalentine Posted November 25, 2014 Report Share Posted November 25, 2014 I really can't say for sure, but a cheaper cat shouldn't be an issue. Link to comment Share on other sites More sharing options...
thefourth Posted November 25, 2014 Report Share Posted November 25, 2014 I agree, buy a cheap universal and have someone pass it. Thanks alaskanzx5 I might just do thatI can recone a sub myself. About a year ago I took 2 12" power acoustic mofos and made one sub. I took the magnet and the motor off of one and j b welded it to the other motor and magnet. I had to wind my own voice coil so it would work. After I was done hooked up to 2 boss 5000w amps. And shattered my back and all my side windows came to this thread to recommend soundqubed and ct sounds. OP goes with soundstream. oh lawd.

Miguels Posted November 25, 2014 Report Share Posted November 25, 2014 you can add the high flow. the only difference i see on stock vs high flow is that the high flow is universal which you will have to cut and weld, stock is a bolt on. if you're not keeping the car there is no need to getting a $500 part for it when you can get it running for $100. you can also clean it by dipping in in soapy water. if you have someone that can help you pass you can remove the internals. my logshttp://www.stevemead...-my-new-set-up/my blow through loghttp://www.stevemead...future-updates/ 96 ss http://www.stevemeadedesigns.com/board/topic/164094-96-impala-ss-build/ Link to comment Share on other sites More sharing options...
OrionStang Posted November 25, 2014 Report Share Posted November 25, 2014 After some quick searching, most companies claim their high flows will pass "most" emissions tests. But not 100% guaranteed. SMD Super Seller My Feedback Thread Link to comment Share on other sites More sharing options...
Keith77 Posted November 25, 2014 Report Share Posted November 25, 2014 what are emissions tests? LOL Thats cool. Im way too old to be upset by shit like that. Your name is winston. Your own parents hated you even before you were born. My penis is bigger than your penis I'm far from loud and my roof/headliner flaps around like Adam's ass on a windy day. I think it depends more on the structure of the vehicle. Link to comment Share on other sites More sharing options...
