For those of you who are running a HKS Muffler (carbon Ti or Not) ... what downpipe, cat/testpipe, and cat back system are u running?? post any fitment issues or power gains.. thnx

 

well most likely going all megan other than my ti/carbon catback. lol. megan dp and hi-flo cat if they have one. i heard good things about them, i believe the megan even has a flex section.

 

+1, i have the carbon ti coming in the mail

 

im leaning towards tanabe for the dp and ur for the hfc

 

i have tanabe 2.75" dp, magnaflow 3" hfc, custom 3" catback piping to carbon/ti hks muffler. on my IX MR

had a issue with hks catback pipe rubbing on driveshaft. thats why i had custom pipe made.
no issues rubbing now with custom piping.

car pulls nice in full boost.

 

I have a helix downpipe, works hi flow cat, and hks ti carbon. Fitment of the the helix downpipe was not good. It kept hitting the transfer case/cross member on mine so had to tweak a little. Everything else fit great.

 

can any1 clafiry if this rubbing issue only on MR's?? or all evo's..

 

i have a works 3'' dp and a custom cat delete pipe then my R&R cat back with hks carbon ti muff

 

I like the sound of my HKS Hi power and there arent any fitment issues with the 8 rear or 9 rear. The only thing is that its not a 3inch exhaust and tapers down towards the tip...not sure about the size but its looks like 2 inches if you look inside the muffler tip. Im changing mine tomorrow to a full 3 inch exhaust...custom made by the shop. With the 35R the HKS exhaust is robbing power big time. I have 3 inch dp, test pipe but with the HKS exhaust it aint cutting it... for stock turbo I guess it aint that bad but for the 35R I need all the flow I need!

 

i thought u have the GREDDY TI!

 

i had this exhaust on my VIII and it was perfect, but it rubbed on my IX.
I have also seen VIII's that rub too. after talking to people with the hks catbacks, its like a hit or miss. its either perfect or it rubs. i guess i was lucky on my VIII but not so lucky on my IX. i love the muffler so thats why i kept the muffler and just had the pipe made, and its all 3" now. the hks tapers down going into the cat

 

I ahve the hks hi power muffler with a same size test pipe and a tomei front pipe and elbow aslo the same diameter as the hks. All of the parts and great quality and excellant fitment. Also not to loud which is good.

 

I did and sold it cause it was too loud. Couldnt stand it and with the new turbo I think I would be death by now. lol
