Hey guys I have been thinking of doing a new exhaust on my 300 and was wondering, how good does the HKS Hi Power exhausts sound? Also what is a good place to get headers and cats brand wise?

Thanks guys

 

Luv my HKS hi power exhaust, they are pretty loud though and a 2 hr drive to my cabin will have your ears ringing a bit. Its a straight through muffler design. I've had my headers on for awhile, some may dislike but they were Ebay stainless steel headers. I bought from someone that had the most pos. reviews. Sounds great and the price was unbeatable. I also wrapped them to keep the temps a lil cooler under the hood. get ready for some bloody knuckles if you plan on doing the headers. They were not fun to install

 

ive also been looking into the too for my 1990 N/A 2+2 and for N/a they say straight pipe it with 2.25 - 2.5 piping and with high quality mufflers for turbo they say the same thing only 3 inch piping

 

i have the hks hi power exhaust on my TT and its somewhat quite. I recently put testpipes in and gave it a nice deep rumble. i thought about straight piping but idk if i can handle that driving to work everyday
