The best way to give your car a treat after 6 years?

[c6pete]

Thought I'd share the news that I finally have taken the leap and am having a new front-to-back system put on the C6! I also realized that I purchased the car 6 years ago today, so figured it's a fitting present for her. Gone with a fully Billy Boat system with Fusion 4 1/2 Oval mufflers at the back, with x-pipe & headers. Hopefully the valves will keep the noise to a decent level when I don't want to wake the neighbours, but will raise hell when opened!

Interesting that you can buy a good quality C6 for the price of a GT86 at the moment, and the new full Cosworth upgrades to take the car to 280hp costs close to 9k (without labour). Imagine what you could do with some of the C6s in the adds at the moment with close to 10k for add-ons. Still one of the best value sports (super) cars out there today.

Will try and get a video done of the final result when it's fitted over the next few days.

For those of you who have done this already - is any tuning needed afterwards? Been advised not, but any thoughts would be appreciated.

Thought people might like to see the finished result of the new Billy Boat system on the C6. Quick drive this morning and it sounds amazing! Having the butterfly valves helps keep the volume in check when needed, which is useful. Minimal drone at cruising speed as well. Happy days all round. Thanks to the guys at Ian Goss for the installation (and 3 working photos!).

Not many Corvette posters round here these days - so thanks to you for flying the flag, and taking the time to most your mods!
Look great and no doubt sounds great too

A good deal of the power increase comes from the x pipe design in the centre section of the exhaust alone - it might well be worth the doing the induction kit side if you havn't already as well, if the cash will stretch to it and then having a remap to integrate everything to best effect.

Great stuff -- keep us posted!

A while ago this forum seemed to develop into discussions on C6 Z06s and not much else. Nothing particularly wrong with that as there were few other contributions, but a lot of regulars went missing.

Try installing headers, the simplest way to release extra HP, x-pipe alone changes the exhaust note a bit, maybe 2 HP if you are lucky. Later models LS3 have x-pipe standard from the factory.

PS C5RagTop is correct, most Corvette discussion in the UK takes place here: www.corvetteclub.org.uk

Yep, that caught me out when I ordered a Borla Stinger system for my '08 - I could have saved a chunk of cash (and shipping costs!) by just ordering the back boxes rather than a full system... Still, 6 years down the line it still sounds great so who's complaining

If you are going to do headers at least have turbos attached to them!

Or what about some supercharged goodness with money left over for someone else to fit / tune

Think I'll be pausing on further mods for the time being, but the induction kit is a probably next step. Already have new long-tube headers so she's pretty set front to back now. Had a blast up to Norfolk and back this weekend for a wedding and had a lot of fun - definitely nice having the option to tone the noise down, especially at cruising speeds.

Also, parked next a nice example of a C4 (D-reg) at a pub called 'The Pigs' nr Holt on Sunday, so hello if you're on here at all. Good to see such a nice example out and about.

Try doing a few rounds with either a turbo or a compressor on the track, not possible. Overheating issues plague even the new C7-Z06, I think GM spend a bit more on research compared to after-market turbo / compressor manufacturers.

Well the ZR1 guys seem to have it pretty sorted. The Magnuson Z06 heat exchange seems to be the key.

The German based Tikt corvette ZR1 seems to be able to run around 850bhp fine on track. A guy on the corvette forum ran a PTK twin turbo (top mount) car on the track for years. You just have to make some cleaver mods.

There is no doubt that NA is better for an out and out track engine (less weight and less to go wrong) but for a fun road car that is also going to see some light track work I cant see why a supercharger couldn't be made to work.

Most if not all unmodified ZR1 guys run hot on the track when pushed. I don't mean quarter mile sprint, but a 20 minute session on Hockenheim for instance. You are correct that Tomislav (TIKT) his ZR1 has no heat problems, have you looked into what he had to do to solve the heat problem. Here's a thread with most of the mods http://www.corvetteforum.com/forums/c6-corvette-zr...

Thomas (TIKT) has a nice thread going about his new project car, a C7-Z06. The thread can be found here http://corvetteforum.de/thread.php?threadid=84013&...

For those who can't read German, I will translate his quote.

"wer will schon einen 660PS Supersportwagen, welcher nur nahe am Polarkreis funktioniert?"

Who wants a 660 hp super car which can only be used on the North pole?

Huge overheating problems come as standard, how to solve them, he is still thinking about it.
