So seeing as to how my exhaust is now holding by a thread, I've decided that it's a pretty good time to upgrade. That means tip to tail, header to.. tail, I suppose. Now, that being said, and with the risk of repeating this question for the 100th time, what is the best complete (and compatible) exhaust system that one could buy for the L61? This will be a simple bolt-on, so no shaving, shimmying, splicing, quantum tunneling or particle accelerating. Obviously, the car will remain N/A. I've honestly looked into going FI, but the costs of something like that is just too rich for my blood. I'm talking about a full on diabetic coma.
Now, I would prefer linear power to come in from mid RPM to redline, rather than breathe through a straw until I get kicked in the back of the head at 5,000RPM. Also, I want it to sound deep and throaty under throttle, but quiet and stock-like at idle, so I guess I'd need some magic resonator or something. Will that cut away from peak power? I hear Borla makes a good sounding cat-back.
Based on my research, 2.25 inch piping would be optimal, as would stainless steel and mandrel bent tubing be. I can never remember the difference between a 4-2-1 and a 4-1 header, but as I explained above, I'd prefer the more linear of the two, even at a slight cost of some ponies. I haven't a clue what makes a good downpipe a good downpipe. Having a freer flowing cat is good, would I need to change the O2 sensors? A superior cat-back system with a resonator and maybe a neat exhaust tip if the option is there. So, I apologize for being all over the place, I'm rather sleep deprived due to insane work hours so I'm a little bit everywhere. I would very much appreciate your opinions and comments, even about where and how to tune the car post installation. I've researched a few places around my area and this place got the most referrals: KNS AUTOSPORT
Looks like they deal mostly with Japanese cars but I guess I'll have to give them a call. Heck, what do I even tell them? Tune my car please? I dunno. Anyways, looking forward to hearing your feedback. Peace.
