I ordered a catbach exhaust a hks high performance for my is350 just waiting to receive it from eBay. I have a takeda intake I was wondering is there any tips or concerns I should know? I don't need a high performance cat do I ? And what's this Megan mid pipe they talk about. Wish I could install myself but I'm sketchy about getting under the car with some 2 ton jacks haha and I don't have air tools. I don't know much about cars but I love everything about them.

Have the same HKS on its way for my 350...best thing is YouTube some of the exhaust clips with the HKS to hear the difference between the different setups. Personally will be ordering the silencers for mine....sounds much better with them. Opinion of course..lol.
