are the catalytic converters for a 94-97 the same as for a 98-01. im pretty sure they arent, but every single ebay auction for them says they are. where can i get a bolt up test pipe that will definately fit my 99 ls?

 

does this bolt pattern look right to you for a 99?

the reason im asking is because i already got screwed once on ebay when i bought a one and it didnt fit. the bolt pattern was a little off and it was too short...

 

All 94+ LS cats are the same length and have the same flanges. The only difference is the second O2 bung on the OBD2 cars.

If you're concerned with fitment issues, I'd avoid the cheap eBay products.

 

well the one that i got didnt bolt up right. at all. it was off a little bit and it was too short. this is the one i bought:

im new on here but ive bought alot of stuff of ebay and got a test pipe for my DA i was kinda worried but it fit but stay away from things that only cost a penny ya know lol

 

kteller sellls some.. You can get a custom sized one made, with whatever flanges you need.

hit em up

 

ok so what did i get in the mail? it says 94-97 gs on it. i have a 99 ls. if those should be both the same size and pattern and everyting...what did i buy?

 

actually obd2 cat bolting is different. the cat bolts straight on my 00 gsr and on my old 95 gsr it bolted side ways.

 

yea thats what i thought. why is everyone saying they are all the same?

 

hey im selling the testpipe that was custom made for me at an exhaust shop and it should bolt up to your car. mine was a 1997 ls. if u are interested lmk. i will measure the length for u if u want assurance. sucks that the ebay one didnt fit

p.s. all the parts i had on the car was stock and it fit, i later got parts that were bolt on. so bolt on header and exhaust and fit perfect with the test pipe.

Because he's talking about the difference between a '00 GS-R and a '95 GS-R, which use completely different exhaust manifolds.

There's really no mystery here. The ITR, '94+ LS, and '00-'01 GS-R all have cats that are the same length with the same flanges. Purchase one designed to fit that application and you should not have any problems.

 

oh alright. thats a weird assortment of years and models with the same ones on it. but yea. mystery solved i guess. no2unenolife, i have a 4-2-1 header and a 2.5 inch cat-back. will the testpipe you have fit? i need an o2 sensor bung too. or an obd1 ecu ha.
