Exhaust compatibility 1G

Looking to go with a HKS Hi Power cat back for my 90 TSI AWD. Will it bolt up to the Megan Racing downpipe or the Apex'i downpipe?

i dunno,why people buying those HKS an other brand exhaust???!!! its waist of money,what i did,Iwent to my local exhaust shop,and they did custom exhaust from turbo all the way to the back,and i payed 450$$ plus an 80 bucks for Megan racing muffler,And im very happy,that i did that,i got very nice,deep sound.and it sound way different,then other dsm's,it sound like a got some kind of bigger cams

It should. Both of those systems should tie in to the OEM catalytic converter. Of course, you'd want to buy a larger cat if you want to do your exhaust.

Like 4G63Powered said yes. Where you run into problems is if you were to use a test pipe from Megan racing or Dejon and then try to bolt that up to an HKS exhaust since test pipes are generally designed for use on a full exhaust system from that manufacturer and the points won't match up throughout the system with anything else.

Thanks for the answers so far. I'm still waiting for my HKS cat back to come in. Then I'll be looking into getting a downpipe.

Well, my HKS Catback is installed. Perfect fit and finish. Now I need a down pipe and a test pipe. I'll be test fitting my buddy's Megan Racing downpipe this week and I'll try to figure out what kind of test pipe to use.

Anyone knows if a Pacesetter Downpipe will bolt on? Thanks

the apexi downpipe is longer than a normal downpipe because it takes the place of the stock cat. your best bet is to buy and hks down pipe then you shouldn't have any problems

HKS doesn't make a downpipe for those cars. I've got a Pacesetter and a Megan Racing downpipe on my desk. I'll be trying them on today or tomorrow.

Well, I got everything hooked up. I ended up using the Pacesetter downpipe with a custom test pipe (vibrant 18inch stainless steel resonator with 1-2.5inch flange welded at each end) and the HKS Hi-Power catback. Hope this helps everyone that is looking around. The exhaust is not loud at all even @ full throttle. The fit and finish of the HKS exhaust is awesome and it doesn't sound ricey at all. All post some pics soon.
